I imported a quiz from a previous class. After importing, I couldn't find it. Turns out that it had the same name as an existing quiz (Exam 2) and it just overwrote it. 

Is there a way to undo?

The worst thing is that now my existing Exam 2 is just gone. All my work on that down the drain unless there's a fix.

Ideas?

btw, can't believe there's not a check for this or an undo or that it wouldn't have the duplicate one be Exam 2(1) or something like every other program in existence. This is such an elementary thing.
