Can a manager edit an approved absence?

We are using Global Payroll and Absence Mgmt 9.2, and HCM 9.2. I believe we are on PUM 48. We have been receiving feedback that it can be a bit of an annoyance to change an absence request once it has been approved (we have automatic approval of our absence entries). If a manager cancels the absence, they need to wait for an absence calculation to run that deletes the absence from the database before they can resubmit or re-enter a new absence. This especially becomes cumbersome if they are just changing the number of hours for the same absence
