Allow instructors to combine results from submissions

Instructors who give an assessment with a single submission can reset (Allow Retake?) for individual student(s). Instructors should be able to see all submissions for reset students.

Suggest enabling the "Highest (or Latest) Submissions" or "All Submissions" dropdown when viewing assessment submissions in which 1 or more of the students have been reset.

Use Case:
Student completes some of the questions in an assessment and gets disconnected or has an issue.
Instructor would like the student to continue and just complete the remaining questions
Instructor resets student submission
Instructor would like to combine results from initial submission with second submission

I'm not sure how you'd handle the case where two submissions have different answers. You'd either have to give the option to accept the earlier/later answer or give the instructor some UI to make the decision (much more complex).
