Add a "All Drug-Tested" Federation Category
There should be a federation category that includes all drug-tested federations.
The filter then needs to be taught which federations are tested: of the ones in the tree currently, those are the USAPL, PA, and IPF.
RPS divisions that include the text "Amateur" or "Elite" are also drug-tested, but I'm not sure how seriously they take that, given that I've never seen RPS report a disqualification due to failing a drug test. I am inclined to exclude them.
I think the major difference between federations, tested or not, really comes down to 24-hr versus 2-hr weigh-ins...
