Edit Flex passes DURING Flex time (in 2 specific ways)#1670

Remove Pass
During Flex, teachers can mark students present or absent (in 3 flavors). They CANNOT delete a pass/remove a student once the Flex time has started. This is a problem when there are students who accidentally signed up for a Flex pass but haven’t notified the supervising teacher ahead of time.

De-select Attendance
Teachers also can’t un-check-in a student - once a selection is made for attendance, it is either present or one of three absents. But sometimes teachers accidentally mark the wrong student present (or absent) - it would be good to be able to de-select the attendance options.
