Payment Method

An invoice has been entered manually, approved and validated with payment method as ELECTRONIC. Since it's an electronic payment the REMIT TO BANK ACCOUNT NUMBER in the header as well as in the Scheduled Payments tab are automatically defaulted from supplier setup. The defaulted bank information was grayed out.

For some reason, we need to change payment method for this specifiic invoice from ELECTRONIC to CHECK but on doing so it won't let me remove the REMIT TO BANK ACCOUNT . I can process it as check but it looks cleaner if we can remove the bank account. Is there a way to remove the bank account by some setting and profile.?
