Prevent B2B communication for a single transaction

Summary: Would like a way to prevent B2B communication of a specific PO

Content (required):

Currently we have "Supplier A" set up to transmit via Colloboration Messaging / B2B. This is working as expected with all purchases orders sent electoronically via OBN. However, we do have the desire to occasionally send a purchase order manually to this supplier.

Is there a way to override at the transaction level to prevent a given PO from being sent electronically and send them email instead
