Re-scheduling jobs when a person leaves

I work in Production Support with several other people.  One of our duties is to schedule Request Sets and Single Requests using the Concurrent Manager Requests process in eBusiness Suite.  For traceability and security, jobs are submitted by our individual User ID.

When a person leaves the group, we need to cancel and reschedule their PENDING jobs to an active employee.  If there are a lot of scheduled jobs, this turns into a big effort.  We take each job, make notes about parameters and run-time, cancel it, and re-schedule it.  It's very tedious and prone to a few mistakes.

Having gone through one of these efforts, I'm wondering if there is an easier way?  Is there a way to simply replace the original submitter's User ID with a co-worker's User ID--either by a screen, CM job, or special SQL?
