Expenses in currency different from base currency

Expenses in currency different from base currency

I have a bank account that is in a different currency from the organisation's base currency.  Expenses are paid out of this account.  My plan won't allow me to have expenses in another currency other than base currency (we are not upgrading).  My question is how do I record and match expenses from my bank statement and overcome this problem?  I have read lot about using the "paid through" account but, tbh I don't understand how it works.  It's not clear at all.  Perhaps someone can explain that one too?
