Well, if there was some commonality between cases and trial groups you'd have
noticed it. How about two event tables, one for each type of schedulable
event and unioning those?
Of course, that's just shuffling the complexity around since you'll need a
view with the relevant rewrites and possibly some way of detecting scheduling
conflicts?
