Pause class for a student during extended absence.

I would love it if there was an option, maybe where you can drop a student from a class, to pause their registration in class. Sometimes we have students with an injury or illness (or other reason) that we know will be absent for an extended period of time. It would be nice to be able to "pause" their enrollment-they would stay on the class list, but maybe show up on the bottom and their name italicized or something on the ipad class manager attendance list, and the personal assistant wouldn't email them if they miss multiple classes in a row.
