对于我正在创建的列表，我想使用以下结构：
IA 1.
但是，使用我正在使用的模板，我可以：
我怎样才能改变列表的这个方面（实际上是大纲）？
这是我的代码：
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{amssymb}
\usepackage{comment}
\begin{document}
\section{Operational rules for constructing an upper line with a basic step motion}
\subsection{The basic step motion}
\begin{enumerate}
\item The final pitch in the basic step motion must be a tonic.
\item The first pitch in the basic step motion must be a tonic triad member a third, a fifth, or an octave above the final pitch.
\item These two pitches must be joined by inserting the pitches of intervening diatonic degrees to form a descending step motion.
\end{enumerate}
\subsection{Beginning of Two-Voice Setting}
\end{document}
谢谢你！

为了enumerate
\renewcommand{\labelenumi}{\theenumi:} % level 1 item signs
\renewcommand{\theenumi}{\Alph{enumi}} % level 1 item number
\renewcommand{\labelenumii}{\theenumii)} % level 2 item signs
\renewcommand{\theenumii}{\roman{enumii}} % level 2 item number
\begin{enumerate} % num:
\item text
\begin{enumerate} % num)
\item text
\item text
\end{enumerate}
\item text
\end{enumerate}
你可以使用这些作为主题
\renewcommand{\thepart}{\Alph{part}}
\renewcommand{\thechapter}{\arabic{chapter}}
\renewcommand{\thesection}{\Roman{section}.}
\renewcommand{\thesubsection}{\Roman{section}.\Alph{subsection}.}
%\renewcommand{\thesubsubsection}{\arabic{subsection}\alph{subsubsection})}
更改编号。
如果你想改变section 编号
\renewcommand{\thesection}{\Roman{节}}
编辑加粗部分。
\renewcommand{\thesection}{（\arabic{部分}）}
