Word totals for discussion visable in speed-grader?

[sepvac]

Hi - I am an instructor, and I typically use word minimums as part of the discussion requirements.  I see the word totals in uploaded papers, but I can't figure out how to do this with discussions.  A search of the community yielded posts that were not germane to my question (i.e., general discussion posts).  

Anyone got any insight on this?
