I have just discovered the "Reassign" button. Can we consider adding another functions?
With the "reassign" button, either allow instructor to change due & close date for that specific student, or bump the due/close date automatically to X days after current date (allow instructor to set X somewhere).
Use case: Often I grade after the assignment has closed (not accepting submission). Using the reassign button, I'm not sure if the due date would be automatically changed for students; so if the assignment is closed, I have to manually edit the assignment and change the due date for that individual.
