Is it possible to change the text shown in \about[...] to be something else than the text given to the titel key of \startsection?

\starttext

\startsection[

  title={Very Long},

%  referencetext={Short}, % <- is there something like this?

  reference=mysec]

  We are now in \about[mysec]. % <- should render as "Short"

\stopsection

\stoptext

I have tried the following, but it introduces vertical white space:

\starttext

\startsection[title={Very Long}]

  \reference[mysec]{Short} %<- introduces white space

  We are now in \about[mysec].

\stopsection

\stoptext

Thank you for any help,

Christoph
