Delete Audit Logs with "changed by" of a specific user

I've identified audit logs, millions of them, that were all changed by a specific user associated with an integration. Is there a way that I can delete all audit logs with a "Changed by" of this specific user? I can go into the Audit Summary View and filter to see only these logs, but as far as I can tell I'd have to select them one by one to delete them, and with 4mil+ of them, that is not feasible. I can identify when these stopped and delete everything on or before that date, but that will delete a lot of other audit history that I'd like to keep. Any help would be greatly appreciated.

Thanks,

Stephen
