Multi Select Function on Form P04572 - Work with Payment Groups - Write Payments

Want to write multiple Bank Accounts for 1 group. 

Work with Payment Groups – Write Payments Multi-Select is not available on form PO4572

>Issue: Must write one payment at a time which has become too cumbersome and laborious for one user processing daily payments. Request multi-select functionality available

Works -Form PO4572 “does” allow all line items displayed on the Write Payments form to be submitted and processed at the same time. 

Please see attached screenshots.

Is anyone experiencing this issue now or in the past? Can anyone help us out with a solution.  According to the manual, a user should be able to write multiple payments withing a group or multiple groups.
