Adding Contract ID to Off-Cycle Payments

Seeking out a solution to add the Contract Number to payments made in off-cycle pay.

When loading contract pay from the PSHUP table, the contract number does not get inserted into the Additional Data automatically, as it does during the paysheets creation process. There is no place to put this data into the PSHUP table, so our payroll group has to manually add each contract number to contract pay individually on each payline for off-cycle adjustments of contract pay.

I am hoping there is a delivered method to accomplish this, and if not if others have found a successful method for managing this. During new academic years in particular we have hundreds of adjustments to do as the year starts.
