Common Paymaster Causing Issues with the SUI files - how does anyone else handle this please?

We have common paymaster setup for our 5 of our 6 payroll companies, with the 6th one being independent.  This works fine for payroll and W2s, etc.

Where it is causing and issue is with the SUI files.  The majority of the SUI files for each state wants the FEIN of the individual company, not the FEIN of the parent company.

There is no place in the Corporate Ids setup to enter the "child" company's FEIN anywhere to report to the states for the SUI files.

We are in the majority of states with 5 of our 6 companies setup as common paymaster, so that is very many SUI F0783xx files we must open and change the FEIN for the specific payroll company.
