Foreign Currency payments from Non functional Currency bank account ?

Foreign Currency payments from Non functional Currency bank account. Is this possible ?

If not then how to handle reconciliation against such scenarios where Ledger currency is USD and transaction currency is also USD but compamny wants to pay from EURO Currency Bank account ?

Can this happen?

In existing situation such entries are passed from GL where they make the payment outside Oracle from EURO bank and directly book JV in GL changing the currency from USD to EURO.
