在引用列表中施加自定义间距

我想在\citep命令列出的参考列表的项目之间设置自定义间距，类似于我在文本中使用“\hspace*”的操作。一种选择是写：

\documentclass{beamer}
\usepackage{natbib}
\begin{document}
\begin{frame}

\citep{A,B,C}\hspace*{5cm}\citep{X,Y,Z}
\end{frame}

\end{document}

但我希望只有一组括号，而不是两组。（也就是说，我想要“(A, B, C, [自定义空间] X, Y, Z)”。

!这是用于标记空格应出现位置的引用命令。!任何引用字符串中只允许出现一个空格。

语法是：

\spcite[<spacewidth>]{<keylist>!<keylist>}

我已将默认间距设置为，3em但可以在定义中更改。
