End Flex Passes#1671

Sometimes students come to a Flex period, but only for part of the Flex time. I’d like to be able to end a Flex pass so students can return to where they were before the Flex period began. For student management purposes, this is an important feature; otherwise, students are either “trapped” in a Flex period, or there is not a way to know they have completed the Flex and are returning to where they began.
