How to set up different currencies on Invoice and Payment at supplier level

Hello! Please, anybody knows how to set up different currencies on Invoice and Payment at supplier level.

For example: I created some supplier, entered a site for payments and purchases.  After this I tried to establish at site level currency for Invoice – USD and currency for Payment – EURO.  But I had an error: “Invalid Payment currency. Payment currency must be the same as the Invoice currency, or an EMU currency”.

I don’t need to have Payment currency the same as the Invoice currency. So how can I manage that the Payment currency would be the same as EMU currency or how to solve this problem in other way?
