Matrix Manager - view Manager's rating and comments

Summary

Looking for a way for the Matrix manager to see the manager's comments prior to finalizing

Content

Looking for a way for the matrix manager to view the manager's comments when they are doing their participant feedback .   It looks like the only way for the Matrix manager to see the comments is once the manager submits his evaluation.  While we can add a final approval where the matrix manager has a chance to reject the manager's comments -- looking for an option where the matrix manager as a participant can have visibility into the manager's view. 

Anyone have success with setting up this requirement  ?
