更大图像内的回忆录标签和参考子图

Question

我有一张包含多个子图的大图像，每个子图都已叠加自己的单字母标题。

我想从文本中引用这些子标题。据我所知，使用子标题及其幻影命令可以实现类似的功能，但我不确定它们是否涵盖了这种特殊情况。

有没有办法从回忆录中做到这一点？

这是一个示例图，可以更好地解释我想要做的事情

这是一张单一图像，我不想拆分它。我想引用子图像，因为它们是单独的图形。

编辑 如果我可以使用的话我会这样做subcaption，不幸的是，当我使用回忆录自己的子图将其加载到文档中时，它就会弄乱所有的标题处理和样式。

所以问题仍然存在，有没有办法制作幻影字幕在回忆录中？

\documentclass{memoir}
\usepackage{subcaption}

\begin{document}
\begin{figure}[t]
  \centering
  \includegraphics{figure.png}
  \begingroup
  \phantomsubcaption
  \label{fig:somefiga}
  \phantomsubcaption
  \label{fig:somefigb}
  \phantomsubcaption
  \label{fig:somefigc}
  \phantomsubcaption
  \label{fig:somefigd}
  \endgroup
  \caption{some caption}
  \label{fig:somefig}
\end{figure}
\noindent Figure~\ref{fig:somefig} has four subfigures:
figure~\ref{fig:somefiga} is a nice fat rectangle, figure\ref{fig:somefigb}
looks good too. Figures~\ref{fig:somefigc}~and~\ref{fig:somefigd} could do
better.

据我所知，仅使用原生 Memoir 宏无法实现这一点。我自己的快速而粗糙的解决方案（绝对没有保证）是引入原始原生宏的略微修改版本（并排差异)：

\documentclass[a4paper,14pt]{memoir}
\usepackage{graphicx}
\usepackage{hyperref}
\hypersetup{
    colorlinks=true,
    linkcolor=blue,
    filecolor=magenta,      
    urlcolor=cyan,
}

\usepackage[all]{hypcap}
