IBAN Validation during supplier Bank account creation

Summary:

We are creating supplier bank account in the supplier master and during bank account creation ,the system allows to reuse the existing IBAN but we have a requirement to prevent IBAN duplicity .

As per my understanding , there is no profile option or standard way to prevent this but Is there are any personalization which can be imposed to prevent this . Kindly suggest.

I came through this profile option in cash management CE_DISABLE_BANK_VAL ,However it is not validating the IBAN.

Thanks

Edwin.
