If I use

\documentclass{article}

\usepackage[toc,page]{appendix}

\begin{document}

\tableofcontents

\begin{appendices}

..

..

\end{appendices}

\end{document}


I get

How can I indent the two sections in the table of contents, so the TOC behaves just like \section{} and \subsection{} with each appendix being indented under the Appendices title just like a subsection would be indented under a section (i.e. same font, the dots between the header and the page number, etc)?

It is really wrong to do stuff like that but here you go.

\documentclass{article}

\usepackage[toc,page]{appendix}

\begin{document}

\tableofcontents

\begin{appendices}
\renewcommand{\thesubsection}{\Alph{subsection}}
