Ver 2.8 - Assignment feedback by more than one teacher

Hi,

I have created an assignment. I want more than one teacher to give the feedback and grading for each student. From what I see, there is one column for Grade and Feedback. If one teacher gives the feedback, then the next teacher has to add to the feedback. I don't see a way of tracking each of the feedbacks/grades separately.

Is multiple feedback tracking possible in 2.8. If so, how.

Thanks for the help.
