Hello, we run sage in GBP, however we do pay some staff in EUR. We now have a euro account but i dont know how this works in sage;

1. how do i set up the bank as it will only let me select GBP

2. If the account is in GBP how do i process the payments out in EUR 

3. How do i account for the exchange rate 

4. Any other advice would be appreciated. 

Thank you
