Shipping Method for Suppliers

Can someone tell me how you can get a shipping method to show up as available in the Users>Suppliers>Editing Supplier: screen? Is it important for this to work if you have a Supplier linked to a Shipping Method, e.g. UPS Ground?

Looks like you do not have any shipping methods “Active”

Actually, what the problem was, is that I had to have my company listed as the Supplier in Shipping/Taxes>Shipping Methods>General tab for this to work in 2.1.2. I think I understood from CsCart support that this was a change in the later versions.
