you can play with this patch

\setvalue{@@description\v!hanging}[#1]#2%
  {\@@dostartdescription[#1]{\def\\{\crlf}}{#2}% % adds \c!margin to 
\leftskip
   \noindent\ignorespaces
   \advance\leftskip -\leftskipadaption \relax
   \ifdim\leftskipadaption=\zeropoint
     \leftskipadaption1.5em % just some default
     \ifnum\insidedefinition=\plusone
       \ifdim\leftskip>\zeropoint \relax
         \leftskipadaption\leftskip
       \fi
     \fi
   \fi
   \ifnum\insidedefinition>\zerocount
     \advance\leftskip \leftskipadaption
   \fi
   \hskip-\leftskipadaption
   \ifhbox\@@descriptionbox\unhcopy\else\copy\fi\@@descriptionbox
   \kern\ifdim\!!widthb=\zeropoint .75em\else\!!widthb\fi
   \ignorespaces
   \@@dodescription}
