Absence Management - Multiple Calendar Groups for Same Period

We are implementing Absence Management 9.2 (PUM38) and need to split our paygroups into multiple calendar groups for the same absence period to allow our Payroll Reps to process absences for the paygroups they process payroll for. We ran through an initial test of how of the setup including having the Generate Absence Payable Time on the Installation settings. And it appears that one Payroll Reps calendar group has to be finalized before the another Payroll Rep can run the Calculate Absence and Payroll process. Has anyone set up multiple Calendar Groups for one absence period?
