Undo Finalize Attendance

We use the the check-in feature on kiosks for the students to check themselves in, which is awesome! However, if someone accidentally hits "finalize attendance" early, it can mark everyone present for the remainder of the day. Students who are coming in for later classes are unable to check-in, and we have to manually update any classes with missing students. It would be great if there was an "undo" for finalizing attendance in the iPad Class Manager to avoid this problem! Thank you!
