Option to default payment term specifically for Credit Memo via FBDI

Summary: Users are uploading large amounts of Credit memos via FBDI. The supplier site has a default payment term, so if they leave it blank in the template, the default payment term is applied which may be associated with taking a discount. Payment processing is very automated in the organization, so if it is not caught, the credit memo may get a discount applied to it based on the payment terms.

I know the users can enter a specific payment term on the FBDI template, but is there any sort of other profile option or other config setting that we have not identified that would overwrite the supplier site payment term for Credit Memos to help prevent the risk of credit memos not being applied in full.
