Remove bullet and leading space before list item

Question

I have some nested lists that I'm trying to format. I would like to remove the bullet and the leading space from the outer list while leaving the inner list unmodified.

Here is some sample code:

\documentclass[10pt]{article}
\usepackage{enumitem}

\begin{document}

\section{Section Title}
\subsection{Subsection Titlte}

\begin{itemize}[label={$\bullet$}, topsep=0pt, itemsep=0pt]
    %
    \item List item with bullet that I want gone
        \begin{itemize}[label={$\bullet$}, topsep=0pt, itemsep=0pt]
            \item Inner list item (I want to keep these bullets)
            \item Inner list item (I want to keep these bullets)
        \end{itemize}
    %
    \item List item with bullet that I want gone
        \begin{itemize}[label={$\bullet$}, topsep=0pt, itemsep=0pt]
            \item Inner list item (I want to keep these bullets)
            \item Inner list item (I want to keep these bullets)
        \end{itemize}
    %
\end{itemize}
\end{document}

Below is an image that shows the output of the above code in the top half. The bottom half of the image shows what I would like my output to look like. I've added the red and blue vertical lines to help illustrate the desired spacing. Note that the desired output removes both the bullet point and the leading space from the outer list. It aligns the text of the outer list with the left side of the deleted bullet point. The inner list remains completely unchanged.

I have attempted to use enumitem to set values for leftmargin, labelindent, and labelsep. However, I can't figure out how to achieve the desired output. Any tips would be greatly appreciated.

Here is a solution:

\documentclass[10pt]{article}
\usepackage{enumitem}
\newlist{balditemize}{itemize}{1}
\setlist[balditemize]{label=, wide=\parindent, labelsep*=0pt, leftmargin=*, topsep=0pt, itemsep=0pt}
\usepackage[showframe]{geometry}

\begin{document}

\section{Section Title}
\subsection{Subsection Title}

\begin{itemize}[label={$\bullet$}, topsep=0pt, itemsep=0pt]
    %
    \item List item with bullet that I want gone
        \begin{itemize}[label={$\bullet$}, topsep=0pt, itemsep=0pt]
            \item Inner list item (I want to keep these bullets)
            \item Inner list item (I want to keep these bullets)
        \end{itemize}
    %
    \item List item with bullet that I want gone
        \begin{itemize}[label={$\bullet$}, topsep=0pt, itemsep=0pt]
            \item Inner list item (I want to keep these bullets)
            \item Inner list item (I want to keep these bullets)
        \end{itemize}
    %
\end{itemize}

\section{Section Title}
\subsection{Subsection Title}

\begin{balditemize}
   \setlist[itemize, 1]{wide=\dimexpr\leftmargini-\fontdimen2\font, leftmargin=*, labelsep =5pt, topsep=0pt, itemsep=0pt}%
    \item List item with bullet that I want gone List item with bullet that I want gone List item with bullet that I want gone List item with bullet that I want gone
        \begin{itemize}
            \item Inner list item (I want to keep these bullets) Inner list item (I want to keep these bullets) Inner list item (I want to keep these bullets) Inner list item (I want to keep these bullets)
            \item Inner list item (I want to keep these bullets)
        \end{itemize}

    \item List item with bullet that I want gone
        \begin{itemize}
            \item Inner list item (I want to keep these bullets)
            \item Inner list item (I want to keep these bullets)
        \end{itemize}
    %
\end{balditemize}

\end{document}

You might want a more automatic approach, but here is an ad-hoc solution:

You could use \item[] combined with leftmargin. By inspecting the values, the default leftmargin seem to be 25pt, and the width of the \bullet seem to be 5pt and the spacing between the bullet and the text also 5pt. Thus the new leftmargin should be 25pt - 10pt=15pt. Also we have to add 5pt to the "inner" left margin (5pt+25pt=30pt) to make up for the distance removed between the bullet and the item: and it actually works as expected:

\documentclass[10pt]{article}
\usepackage{enumitem}
\begin{document}

\section{Section Title}
\subsection{Subsection Title}
\begin{itemize}[label={$\bullet$}, topsep=0pt, itemsep=0pt]
    %
    \item List item with bullet that I want gone (below)
        \begin{itemize}[label={$\bullet$}, topsep=0pt, itemsep=0pt]
            \item Inner list item (I want to keep these bullets)
            \item Inner list item (I want to keep these bullets)
        \end{itemize}
    %
    \item List item with bullet that I want gone (below)
        \begin{itemize}[label={$\bullet$}, topsep=0pt, itemsep=0pt]
            \item Inner list item (I want to keep these bullets)
            \item Inner list item (I want to keep these bullets)
        \end{itemize}
    %
\end{itemize}

\begin{itemize}[label={$\bullet$}, topsep=0pt, itemsep=0pt, leftmargin=15pt]
    %
    \item[] List item with bullet that I want gone
        \begin{itemize}[label={$\bullet$}, topsep=0pt, itemsep=0pt, leftmargin=30pt]
            \item Inner list item (I want to keep these bullets)
            \item Inner list item (I want to keep these bullets)
        \end{itemize}
    %
    \item[] List item with bullet that I want gone
        \begin{itemize}[label={$\bullet$}, topsep=0pt, itemsep=0pt, leftmargin=30pt]
            \item Inner list item (I want to keep these bullets)
            \item Inner list item (I want to keep these bullets)
        \end{itemize}
    %
\end{itemize}
\end{document}
