specific vendor notes on purchase orders

Hello,

I would like to be able to add notes to a printed/emailed purchase order document, only for specific vendors. Example - Vendor 1 needs to call our 3PL to arrange for pick up and delivery every time we purchase from this vendor. I want the 3PL phone number and email address to appear on the purchase order document we email to this vendor. Vendor 2 will not be calling our 3PL for pickup and delivery so the 3PL information should never appear on the purchase order document we email to vendor 2. Is there someplace we can add specific notes
