Multiple shipment origins- CA and US.??? Possible???

Is it possible to have two separate shipment origin locations whereby all orders to Canada ship from a Canadian location and rates are caluclated with CanadaPost and all shipments to the US originate from a US location and calculate using UPS. Neither of the modules seem to have an entry for a ship-from-address like the fedex module does.

Does anyone know how to set it up as such?

Thanks, much.

Should be possible since you are also referencing 2 different carriers.

Set up a shipping zone for Canada and separately United States using Admin->Localization->Zone Definitions

Then Admin->Modules->Shipping...For the Canada Post set Shipping Zone for Canada. For the USPS, set the same for United States.

Once set, CP will only be available to Canadian ship-to addresses, and USPS for US addresses.

edit--
hmmm...looks like USPS you don't set originating address like UPS or FedEx. Not sure if CP module allows it or not. If CP does, then you can set Zen Cart with a default US address for USPS, and CP module would use Canadian origin (if module allows for this).
