Notes section within each Supplier

A free text "Notes" section within each supplier. It would allow me to enter data such as: -Delivery free if orders over £XX (and list delivery costs for orders below this value) -send POs via email -place orders on XXX (web address) Some of my suppliers have multiple ordering platforms and which I have to use, depends on the brand I'm ordering...it would be really handy to have a notes section so I can list these details.
