Not in org AFAIK, org only supports these for my use cases not very useful 
"function name = " exports.  I patched org to produce real captions instead, 
but my changes are not that well tested and required some changes in the 
central export logic.  If there is interest I could share what I have so far.  
The code quality is a mess, as I do not really know elisp.
