Lyx、Beamer 和 itemize

Question

因此，我尝试使用 LyX 和 Beamer 来创建演示文稿。当我尝试在 LyX 中使用 itemize 时，我希望它看起来像这样：

\begin{itemize}\raggedleft
\item ניסיון
\end{itemize}

我可以不手动输入 LaTeX 代码来做到这一点吗？谢谢。

编辑：这是一个例子：

这是使用 XeTeX 的结果：

您可以用以下方式替换和\raggedright定义中的硬编码：itemizeenumeration\raggedleft

% !TeX TS-program = xelatex
