Is there a way to restore rubric feedback on an assignment?

Options

I have an instructor that needed to change the rubric they used in an assignment and when they changed the rubric utilized for the grade, it properly transferred the total grade for the assignment but the in-line feedback and criteria scores were lost (and as this is a public speaking class the feedback is very important).

 

Since the feedback would have been autosaved when the assignment was originally graded, is the data logged somewhere that it can be restored?
