This can be set up with the "way=bysomething" keys, most variables permit
this. 

\starttext

\startsectionblockenvironment [bodypart]
  \setupcaptions[way=bytext]
\stopsectionblockenvironment

\startsectionblockenvironment [appendix]
  \setupcaptions[way=bychapter]
\stopsectionblockenvironment

\startbodymatter
  \chapter{test} \placefigure{}{}
\stopbodymatter

\startappendices
  \chapter{test} \placefigure{}{}
\stopappendices

\stoptext

\setuppagenumbering[chapternumber=yes]
