SSRS Change Log - Automatic Log of changes made within SSRS

We are on Epicor 10.2.700, and were recently acquired by a large Public Company. We are now being told we need to put controls in place to ensure SOX-compliance. Once of the controls is to automatically Log changes to SOX-Relevant Reports. I know how to use Change Logs within Epicor to track changes to records, but we are being told we also need to be able to show all changes made to SSRS reports within SSRS. I am just wondering if anyone else has dealt with this and knows of a solution? Thanks!
