Reassign Credit Reviews automatically

I know that an approver can turn on their Vacation Rule to delegate their approval authority to another person. But has anyone figured out a way to automatically reassign Case Folders to Credit Analyst B when Credit Analyst A is out of the office (vacation, sick, travel, whatever)? Yes, I know that you can manually reassign Case Folders from the Credit Scheduler function. But that can be a tedious process, especially if you have many Case Folders being generated throughout the day. Is there any way to automate that process?
