How to restrict employees for adding bank account once only

Content

Hi All,

Please suggest solution around it.

Requirement : 

Employees should not be allowed to add more than one bank account information. However since system allows to add multiple bank accounts, therefore the question is how do we decide which bank info needs to be sent to third party Payroll vendor. Client ask ,is if we can have some flag there which will mark that those specific bank details only needs to be sent to payroll vendor, that would help to resolve it. 

This is for an Indian client. We are on release 21 B.
