Account Permissions in Separation Model

Is it possible to have user accounts only in the main file and use a separate admin-like account for the other 4 files?
It is very difficult adding and updating user accounts to all 5 files after an update. The migration tool helps but is not flawless.
Would really like to have user accounts only for the main file.
