Item Analysis of Advanced Grading Methods

For a given assignment, I would like to be able to do an item analysis for each criterion in an advanced grading method (similar to how you can evaluate results for a quiz using the Grade report.) I see this as being a Results link in the Navigation menu similar to how quiz has one that allows teachers to view a report of all users and scores for each criterion. This would allow teachers to identify areas the class may be struggling with in a particular assignment.
