Choose if you show Dropped Students in Attendance History of a Class

It would be nice if we could choose to show those student in attendance history or not.
Or at the very minimum dropped students get removed from the alphabetical listing and are in a separate "dropped" section. At the beginning of the year we move dancers around a lot to ensure they are in the best class. This is leading to ridiculous class attendance history and making looking at it virtually useless.

Thank you.
