Couldn't you just "Pick every unit in (unit group) matching (conditions)"?
there is no single GUI action that I know of which can do this. actually, what I suggested is a quite short way, will require like three actions for deciding each random unit, and its possible to make it completely leak-free

Don't double post.
There is no way to use GUI Groups without leaking...
