Bulk assignment of supplier bank account from FBDI at site level

Summary:

We have scenerio where we already having supplier bank account defined in application and during roll out phase we want to use the same bank account with multiple new business unit that we are creating as part of roll out.

Please advice, should we use supplier bank account FBDI to assign this bank account to supplier. I am afraid does not create another record with same bank account in oracle. Our purpose is only to assign existing bank account to new supplier sites that we created. Do we have any way where we can existing bank account to new Business unit instead of creating the new duplicate bank account ?
