Automatic enumeration after customizing one item (\enumerate)

Question

I have a numbered list, labeled: (1), (2), ... (see photo)

I would like to have a * after some of those numbers (not all of them), as shown on the photo.

I have done it by using command \item[(2)*] (see below), but the program stops to count items at this line and I must set numbers for all following items manually. Is there a way to do this and keep automatic enumerating?

\documentclass{article}
\usepackage{enumitem}
\setlist[enumerate]{align=left}
\begin{document}
    \begin{enumerate}[label={(}\arabic*{)}]
        \item Random text
        \item[(2)*] Random text
        \item[(3)] Random text
        \item[(4)] Random text
    \end{enumerate}
\end{document}

Answer 1

Since you say that not too many enumerated items get a star affixed to the numbers, you could just execute \refstepcounter{enumi} after, say, \item[(2)*], to increment the applicable counter variable. (Aside: the counter variables associated with level-1 through level-4 enumerated lists are called enumi, enumii, enumiii, and enumiv.)

Choosing this method will also let you cross-reference any of the items via the usual \label-\ref mechanism.

\documentclass{article}
\usepackage{enumitem}
\setlist[enumerate]{align=left}
\begin{document}
    \begin{enumerate}[label=(\arabic*), ref=\arabic*]
        \item Random text
        \item[(2)*]\refstepcounter{enumi} Random text \label{item:b}
        \item Random text
        \item Random text \label{item:d}
    \end{enumerate}
A cross-reference to items \ref{item:b} and \ref{item:d}.
