We have a rule here that students can not have more than two major assignments due on the same day. It would be great to have the ability to mark things as Major Assignments in BB, and then keep students from being given more than a certain number each day, natively. So for example, Johnny can have a math test and a physics presentation on the 12th, but then if the language teacher tries to schedule a test, they get a notiece that the kid is overscheduled and they have to pick a different day.
