Unmark as graded
With the pregrading MC we have "a" for approve, can we add a shortcut to "unmark" something as graded.
Use case: we are double checking exams, and a TA has something they want to discuss with me. Marking it as not graded (but keeping the rubric filled), allows us to easily find it.
(Currently I use some SQL queries like:
UPDATE solution SET grader_id = NULL, graded_at = NULL WHERE solution.submission_id IN ( SELECT id FROM submission WHERE submission.student_id IN () );
to mark things for double checking)
