General ⇒ Renaming Titles of (Sub)Appendices for ToC

[pretentious_indifference]

Hi all,

Have been struggling for quite some time to format the title of chapter appendices (subappendices) for ToC. The following works alright:

\documentclass{article}
\usepackage[titletoc,title]{appendix}
\begin{document}
\tableofcontents
\section{First Section}
\begin{subappendices}
\subsection{App1}
hehe
\end{subappendices}

\end{document}

which produces the entry "Appendix 1.A App1" in ToC. I wanted to change it to something like "NewAppendixName A App1" with the following command:

\renewcommand{\appendixtocname}{NewAppendixName}

Unfortunately it does not work and nothing gets changed.

Can anyone suggest a hint or something...

Cheers
