# Hang section number, but not subsection number in Memoir

I use the memoir class to control my document. I have placed the section numbering in the margin with \hangsecnum, but I don't want the subsection and subsubsection numbering in the margin.

How do I prevent this?

Using the sectioning hooks would be an easy way:

\setsechook{\hangsecnum}
\setsubsechook{\defaultsecnum}
\setsubsubsechook{\defaultsecnum}


Edit: here's a minimal working example, according to the comments:

\documentclass{memoir}
\setsechook{\hangsecnum}
\setsubsechook{\defaultsecnum}
\setsubsubsechook{\defaultsecnum}
\begin{document}
\chapter{One}
