Ability to extend payment instruments LOV

We are currently on Oracle EBS v12.2.10.

We leverage credit card payments which are tokenized for authentication/settlement which can result in multiple payment instruments with similar values including the encrypted card number, cardholder name etc..

When a user accesses the receipts form and wishes to apply a credit card, when the window for payment instrument details is launched, the associated RG for credit card number has a pre-determined series of columns (card brand, number, expiration status, card holder name).

It would appear this is entirely driven by an associated PLL which overrides any attempt to create a record group.
