Payments from multi-currency bank accounts

[voxelias]

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?

Do you know if it is safe to always supply the currency even with non.multicurrency accounts?

Well, it is even defined by the schemas in your repo
