Worker bank account IBAN validation in 7.3

Hi all,

I noticed when I enter an IBAN number within Worker --> Employees --> Bank accounts, it does not perform a validation check. So if I enter the wrong format by accident, I wont be informed about that. The validation is present in Cash and Bank management --> Bank accounts --> Bank accounts. (other entity)

In 7.1 it was possible through setup in Bank groups but apparently this changed in 7.3. Is there a solution (setup) possible or is development needed? I can't find any useful information about this issue.

Thanks.
