PeopleSoft 9.2 Procurement Card Prepayment Voucher - need credit card details not summary

We've selected the method Procurement Card Load Voucher Stage option of Create Vouchers "By Credit Card Number".    However, the Prepayment Voucher still creates only a summary entry.   This means there is NO detailed information to send in the ACH payment so the credit card provider knows how to the apply the payments to the credit card transactions being paid -- no credit card number, no amount.    This is why we selected the "By Credit Card Number" rather than "By Business Unit".

How do we get this to function correctly?   This seems like a bug.   The ACH (or even check statement) MUST contain the details in order for the payment to be applied.    You get the same result regardless of which option you use (By Credit Card or By Business Unit).    The non-prepayment (approved/reconciled transactions) DO get created as single vouchers per credit card, but that doesn't help.    This makes the prepayment feature pretty useless.   Help!!
