It should be possible to open balance sheet accounts in foreign currencies so suppliers / customers accounts in foreign currencies can be posted to these. This would then give a consolidated view of how much is owed in each currency. Of course, on the balance sheet itself the values would be restated back to the base currency, but having foreign currency AP/AR accounts would make sure you can manage those currencies better. I know that QuickBooks has this functionality.
