Change Documents for RAR

We use RAR 5.3 SP 14 and were wondering if there were any tables or reports that can show the change history upon mitigation added to a user. We can see the date that the mitigation was assigned to a user, but we can't seem to find the date when a mitigation was removed from a user.

For those that are questioning, we do use CUP for mitigations too, but we are mainly trying to find the change documents for RAR.

Thank you in advance.
