I clicked "duplicate" on a test in new quizzes from a previous grading period in order to make a duplicate so I could assign it to a student currently.  I see the 'Some settings have been disabled because the assignment is in a closed grading period' message in blue, so therefore I cannot make edits.  Shouldn't I be able to do this on a duplicate, so I won't have to build the whole test again?  All I want to do is change the "assign to", the availibity dates, and the due date, so that this student can take the test.  Can you help?
