Hello!
Some bank offers multi currency accounts, when under the same account number you have separate accounts for different currencies. Such banks expect to receive <Ccy> in <DbtrAcct>:
<DbtrAcct>
<Id><IBAN>CZ7855000000005001264780</IBAN></Id>
<Ccy>EUR</Ccy>
</DbtrAcct>
It seems that the library does not support it now. Do you consider having it?
If I submit a PR, how would you like it to be implemented? multi_currency=True in config or something else?
