We have multiple locations that we ship from. These locations do not share the same carriers and when they do they have different carrier accounts. We need a way to be able to setup each shipping location with its own set of carriers.
We do not want people from location 1 to be able to pick location 2 shipping carriers.
i.e. Shipping Location 1 => UPS Accout1, Fedex Account1, Shipping Location 2=> UPS Account2, FedEx Account2
