更改具有自定义简写的 biblatex 引文的格式

Question

考虑一下这个MWE：

\documentclass{article}
\usepackage{filecontents}
\usepackage[style=alphabetic]{biblatex}

\begin{filecontents}{biblio.bib}
    
  @inproceedings{Duck23,
    author = {Donald F. Duck},
    title = {How to get away with Scrooge},
    booktitle = {Proceedings of the 42nd International Conference of Fictional Characters},
    year = { 2023 },
    shorthand = { ICFC~23 }
  }
    
  @inproceedings{Mouse99,
    author = {Mickey Mouse},
    title = {Dealing with Pete for fun and profit},
    booktitle = {Proceedings of the 18th International Conference of Fictional Characters},
    year = { 1999 }
  }

\end{filecontents}

\addbibresource{biblio.bib}

\begin{document}

Our previous work~\cite{Duck23} differs from others in the literature~\cite{Mouse99}.

\printbibliography

\end{document}

结果是这样的：

当我在文献中引用作品和我自己发表的出版物时，我正在为申请写一封求职信。我的出版物有一个简写，可以让人想起它们发表的会议或期刊（比如[ICFC 23]在 MWE 中）。然而，区分我自己的引用和文献引用并不总是那么容易。所以我想用不同的字体排版，也许是粗体、斜体，或者其他什么。

那么有没有办法告诉biblatex只更改具有自定义简写的引用的格式？
