Canceling old Proofs- bulk closing/decision making

We are hoping to utilize the "awaiting my approval" widget on the new homepage.  The problem is historically we have not been great about requiring proof decisions, so we have thousands of proofs from over the years to clear out.  Is there a way to do this, in bulk would be ideal. Some of these proofs are from 2018 and have automatically been archived, but they still show up as awaiting my approval if not everyone made a decision.

Help please 🙂
