Absence Plan with Multiple Absence types

Summary:

We have a requirement to create multiple absence types for a single absence plan. The purpose is to record PSL hours under one type and PTO under a separate type.

The absence type used to request PSL time needs to be capped at a specific number of hours, (let's say 40 hours for example) and if selected after the cap is reached, do not allow the entry of the hours.

The employee is eligible for 200 hours, 40 hours will be used for PSL. Once 40 hours of PSL has been reached do not allow any further request for the PSL type.

Has anyone ever implemented a scenario like this one?
