R44H702 Auto-Voucher combining multiple company PO's into one Voucher

We have a Homebuilder client that runs the Auto-Voucher creation (R44H702) fairly wide open. They have the Processing Option on the P4312 to NOT create a separate Voucher for each PO.

As a result, there are multiple PO companies on one voucher. The companies are often not the same (i.e. the same supplier works on different jobs/communities) so there are different POs with different companies on the PO's that do not line up with the Company # of the Voucher.

If they need to reverse a Voucher match, when the Voucher is selected for Voucher Match Reversal, the list of PO's called is empty. I am fairly certain it is due to the company being different for the associated PO's vs. the Voucher Company. Mutiple PO's on a voucher in the same company as the Voucher are fine.
