Ability to allow duplicate receivable invoice numbers on Project Invoice

We are trying to update a few project invoices with same receivable invoice number.

We created a contract invoice in AR through FBDI by combining multiple project invoice lines. Now, as a part of tieback, we wanted to update the Receivables number back to Project invoices which were combined.

We are able to update the receivable invoice number on first project invoice using API, but when we are trying to update remaining project invoices we are getting below error:

Receivables Number: The receivables invoice number must be unique. (PJB-2190177)

Is there a way to remove the above restriction?
