自動枚舉多個註腳 marginnotes tufts-style-book

Question

我想在禁止模式下自動枚舉多個腳註（簇狀邊距註釋）。目前，我可以指定腳註編號並將註釋放置在分項清單下方，但我希望它內聯。任何人都可以幫助或提出建議如何做到這一點？世界行動通訊大會如下：

\documentclass{tufte-book}
\usepackage{microtype} % Improves character and word spacing
\title{Sample: \\ Book \thanks{Thanks}} % Title of the book
\author[author]{author} % Author
\publisher{publisher} % Publisher

\begin{document}

\begin{multicols}{2}
\begin{itemize}
\item sample \footnotemark[1]
\subitem sample
\item sample\footnotemark[2]
\subitem sample
\item sample
\item sample\footnotemark[3]
\subitem sample
\item sample\footnotemark[4] 
\subitem sample
\item sample
\subitem sample
\subitem sample
\subitem sample
\subitem sample
\item sample\footnotemark[5] 
\item sample\footnotemark[6]
\end{itemize}
\end{multicols}

\footnotetext[1]{sample}
\footnotetext[2]{sample}
\footnotetext[3]{sample}
\footnotetext[4]{sample}
\footnotetext[5]{sample}
\footnotetext[6]{sample}

\end{document}
