Another Open Assessment Question

I’m looking to build an Open Assessment question with a single pass/fail question that when failed by the instructor, can be re-answered by the learner. We’ve figured out that you can do this by cancelling their answer, but the instructor’s feedback then disappears, as does the original answer. Is there a way to retain the original answer and instructor feedback?

Also, is there anyway an instructor can be notified via email when a student has submitted?
Thank you all.
