multiple inputs for same currency?

is there a way to define multiple same currencies? for instance 2 USDs, that can be associated with two regions, for example an international region and US region both prices are in USD but the international region associates with the 2nd USD and has a different price. It seems the case you can use USD multiple times to get the input within 'prices' but there's no convenient way to specify which USD belongs to which region, they will just associate with the first USD price.
