修改命令以获取替代图表列表

Question

我想要一个经过修改的\listoffigures命令（名为\mlistoffigures），它从一个额外的命令（名为）中获取为图形打印的文本。您能帮我定义这两个命令吗？如果也适用于图形（如） \extracommand，那将很有用。\extracommandnon-floatcaptionof

我的MWE如下：

\documentclass{article}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{subcaption}
\usepackage{duckuments}

\captionsetup[subfigure]{list=true}

\begin{document}

\listoffigures
\mlistoffigures %command to be defined

%
%Desired output of \mlistoffigures (using \extracommand{}):
% 1. Fig. 1
% 2. Fig. 2
%    a Fig. 2a
%    b Fig. 2b

\begin{figure}
\centering
\includegraphics{example-image-a}
\label{fig:alef}
\caption[Alef figure.]{Alef.}
\extracommand{Fig. 1} %command to be defined
\end{figure}

\begin{figure}
    \begin{subfigure}[]{\textwidth}
    \centering
    \includegraphics[width=\textwidth]{example-image-b}
    \label{fig:bet}
    \caption[Bet figure.]{Bet.}
    \extracommand{Fig. 2a}
    \end{subfigure}
    
    \begin{subfigure}[]{\textwidth}
    \centering
    \includegraphics[width=\textwidth]{example-image-c}
    \label{fig:gimel}
    \caption[Gimel figure.]{Dalet.}
    \extracommand{Fig. 2b}
    \end{subfigure}

    \caption[Bet + gimel figure.]{Bet + gimel.}
    \extracommand{Fig. 2}
\end{figure}

\end{document}

我认为这个答案符合 OP 的要求，正如他在我之前的交流评论中所说的那样。

** ORIGINAL POSTING**

Not an answer but it shows what I tried. After your above comment I did not understand the basics of what you are after. I tried for a new `listof...` but after some failures I gave up (although I'm sure that it is possible) ---time constraints came into this. 

I thought that perhaps what you needed was just to list the figure numbers. Below I have done that by using `\ref{<fig-label>}`. I had to modify your original code as `\label` has to come after `\caption`.
