Commercial Invoice currency default by store
If I had it my way I would ask for the commercial invoice currency to be defaulted by store and manually switchable in the customs information section for each order. This way the correct details (including currency) are submitted to this shipper before the creation of any customs documents. And the shipper should have full control with the ability to default the currency based on the specific store or marketplace.
