How to run the Evaluate Absence process for more than 300 employees at a time in an absence?

Some changes were done in Sick Leave Plan. The employees who have already applied for this leave before changes need to reflect with the new changes. We can run Evaluate Absence Process to get the new changes. But our question is there are 300+ employees applied for this leave before. Do we need to run that Evaluate Absence Process 300 times? Or Is there any other method.
