Not removing credit card expiration date

Is there a way to NOT remove the credit card expiration date info while removing the card number?

In order to process refund through, we need the expiration date.

Can we configure this or does it have to be modded?

Does anyone have this mod?

It would have to be a mod to fn_cleanup_payment_info() in core/fn.cart.php.

I think I see where it is. Thank you very much!

Yeah, it’s an array of fields. Just delete the ones you don’t want it to delete/overwrite.
