Thanks for your reply. Yes I think a link back would help.
What our tutors were hoping for was a quick and easy way to look back over the feedback the student has attained over all assignments to gain an overview of their progression when writing reviews. Because we use feedback files this currently means going into every assignment individually. The link from the grader report would still mean going into each assignment individually, if I understand correctly, because it would take the tutor away from the grader report page containing all of the links, but yes, I do think it would be easier to navigate.
