Could an existing pending approval expense report be available to newly setup prepay auditor?

Scenario:

1.) Employee submitted an expense report and is now pending approval by a prepay auditor.

2.) Thereafter, a new user is setup and assigned as a prepay auditor.

Is there a setup that will make available the pending approval expense report available to the new prepay auditor although the said new prepay auditor was setup only after the expense report was submitted? What is the alternative if such setup or process is not available?
