Creditors / Clients with IBAN/BIC

So, I want to have creditors / clients with an IBAN / BIC fields, so that my MT940 Import could sync to these fields. Also the bank name could be useful.

For me, this should be implemented in core, not be added through APP custom-fields, cause it is a very basic need. Also the current N/V values for Creditors / Clients aren't very helpful.

Maybe some of the app developers give a response. I really would appreciate your opinion/agenda on this.

still, would be very much appreciated
