Keep "Appendix #" in the appendix title, but remove the appendix from the table of contents

Question

I'm writing a PhD thesis, and my university requires that I list the appendices in a "List of Appendices" (LOA) that is separate from the main table of contents (TOC). I've successfully created a LOA using the tocloft package. The problem is that the appendices are still also listed in the TOC.

One unsatisfactory workaround is to use the asterisk'ed forms of \chapter and \section in the appendices. Among other reasons, I don't like this because it removes the appendix letter from the appendices' title pages.

How can I keep the appendix numbers in the LOA, but remove them from the TOC?

I am using the appendices, tocloft and quotchap packages.

Below is a minimal compilable example.

\documentclass[12pt,draft,letterpaper]{report}
\usepackage{quotchap}
\usepackage[titles]{tocloft}
\usepackage{appendix}

\newlistof{appendixchapter}{apx}{List of Appendices}

\newcommand{\appendixchapter}[1]{%
  % These three lines are needed to list the appendix letter in the List Of
  % Appendices even when using \chapter*
  \refstepcounter{appendixchapter}%
  \refstepcounter{chapter}%
  \providecommand{\DOTIS}[1]{\DOCH \DOTI{#1}}

  % '*' removes the appendix from the table of contents.
  \chapter*{#1}

  % Lists the appendix in the List of Appendices.
  \addcontentsline{apx}{appendixchapter}{Appendix \protect\numberline{\theappendixchapter}#1}\par%
  \vspace {-1.47cm}}

\renewcommand{\theappendixchapter}{\Alph{appendixchapter}}

\begin{document}

\tableofcontents
\listofappendixchapter\addcontentsline{toc}{section}{List of Appendices}

\chapter{My first chapter}
This is Chapter 1's body.

\appendixchapter{My first appendix}
This is Appendix A's body.

\appendixchapter{My second appendix}
This is Appendix B's body.

\end{document}

Answer 1

There's really no need to define a new command for the chapter in the appendices section; just before the appendices you can redefine the \@chapter command (defined in report.cls), to include the appendices in the new list instead of including them in the ToC; here's an example of such a redefinition; note that the second mandatory argument of \newlistof must be used in the redefinition of \chapter (see the lines marked with %NEW):

\documentclass[12pt,draft,letterpaper]{report}
\usepackage{quotchap}
\usepackage[titles]{tocloft}
\usepackage{appendix}

\newlistof{appendixchapter}{apx}{List of Appendices}

\begin{document}

\tableofcontents
\listofappendixchapter
\addcontentsline{toc}{section}{List of Appendices}

\chapter{My first chapter}
This is Chapter 1's body.

\appendix

\makeatletter
\def\@chapter[#1]#2{\ifnum \c@secnumdepth >\m@ne
                         \refstepcounter{chapter}%
                         \typeout{\@chapapp\space\thechapter.}%
                         \addcontentsline{apx}{chapter}%NEW
                                   {\protect\numberline{\thechapter}#1}%
                    \else
                      \addcontentsline{apx}{chapter}{#1}%NEW
                    \fi
                    \chaptermark{#1}%
                    \addtocontents{lof}{\protect\addvspace{10\p@}}%
                    \addtocontents{lot}{\protect\addvspace{10\p@}}%
                    \if@twocolumn
                      \@topnewpage[\@makechapterhead{#2}]%
                    \else
                      \@makechapterhead{#2}%
                      \@afterheading
                    \fi}
\makeatother

\chapter{My first appendix}
This is Appendix A's body.

\chapter{My second appendix}
This is Appendix B's body.

\end{document}

An excerpt from the resulting document showing the ToC and the LoA:

As requested, here's the code necessary to use a new command \appendixchapter (similar to \chapter) for the appendices; the new definition needs two new commands \appendixchapter and \@appendixchapter; only the first one will be used in the document body:

\documentclass[12pt,draft,letterpaper]{report}
\usepackage{quotchap}
\usepackage[titles]{tocloft}
\usepackage{appendix}

\makeatletter
\newcommand\appendixchapter{\if@openright\cleardoublepage\else\clearpage\fi
                    \thispagestyle{plain}%
                    \global\@topnum\z@
                    \@afterindentfalse
                    \secdef\@appendixchapter\@schapter}
\def\@appendixchapter[#1]#2{\ifnum \c@secnumdepth >\m@ne
                         \refstepcounter{chapter}%
                         \typeout{\@chapapp\space\thechapter.}%
                         \addcontentsline{apx}{chapter}%NEW
                                   {\protect\numberline{\thechapter}#1}%
                    \else
                      \addcontentsline{apx}{chapter}{#1}%NEW
                    \fi
                    \chaptermark{#1}%
                    \addtocontents{lof}{\protect\addvspace{10\p@}}%
                    \addtocontents{lot}{\protect\addvspace{10\p@}}%
                    \if@twocolumn
                      \@topnewpage[\@makechapterhead{#2}]%
                    \else
