You can track the username of the user who has performed the action on the management pack, but you cannot give the criteria specifically for creating/modifying the override in the report. You will see the previous and the new override value in the report.
I have blogged about the change tracking reports over here:

If you have any suggestions, feel free to give them over at the SCOM uservoice page over here:
