Indenting lines of expex within a list?

Question

I'm having difficulty forcing expex to indent correctly with its containing element. Does anyone know how to force expex to indent? Below is a code snippet:

\begin{enumerate}
    \item First piece of evidence for a phenomenon with examples below.
    \ex \label{anexample}
    \begingl
    \glpreamble \textit{No hablamos}//
    \gla no habl-amos //
    \glb \textsc{neg} speak-\textsc{pres.indic.1pl} //
    \glft `We don't speak.' //
    \endgl
    \xe
    \item 
\end{enumerate}

The problem I am having is that the nested expex code always has the same indent (across the entire document), in this instance it appears to the left of the enumerated item. I want expex to dynamically indent to match its containing element, is this possible?

You can use the numoffset parameter to indent an example. This is described on page 11 of the documentation. The relevant length inside a list is \leftmargin:

\documentclass{article}
\usepackage{expex}
\begin{document}
\begin{enumerate}
    \item First piece of evidence for a phenomenon with examples below.
    \ex[numoffset=\leftmargin] \label{anexample}
    \begingl
    \glpreamble \textit{No hablamos}//
    \gla no habl-amos //
    \glb \textsc{neg} speak-\textsc{pres.indic.1pl} //
    \glft `We don't speak.' //
    \endgl
    \xe
    \item 
\end{enumerate}
\end{document}

If you have a lot of these enumerations, you can use the enumitem package to set the indents at the list level:

\documentclass{article}
\usepackage{expex}
\usepackage{enumitem}

\setlist[enumerate]{before={\lingset{numoffset=\leftmargin}}}

\begin{document}
\begin{enumerate}
    \item First piece of evidence for a phenomenon with examples below.
    \ex \label{anexample}
    \begingl
    \glpreamble \textit{No hablamos}//
    \gla no habl-amos //
    \glb \textsc{neg} speak-\textsc{pres.indic.1pl} //
    \glft `We don't speak.' //
    \endgl
    \xe

\end{enumerate}
\begin{enumerate}
\item Another list
    \ex \label{anexample}
    \begingl
    \glpreamble \textit{No hablamos}//
    \gla no habl-amos //
    \glb \textsc{neg} speak-\textsc{pres.indic.1pl} //
    \glft `We don't speak.' //
    \endgl
    \xe
\end{enumerate}
\end{document}
