Absence type recorded on a public holiday is paying double

We have a requirement wherein payroll admin needs to have the ability to delete (or over-ride) the holiday schedule for any employee and replace with any absence wage type, resulting in the employee receiving only the appropriate number of hours in payment for the date of entry.

To simplify, when i record a FMLA (absence type) on a public holiday, then the system should pay me only for FMLA not for public holiday. Right now, it is paying for both public holiday and FMLA.

Can we do a workaround in the counting rules to achieve this functionality?
