We need a way to create custom designations for subaccounts that cannot be changed or seen by the account admin/user.

I have an automation that assigns an account number to each account. This same account number is used in ad accounts, analytics platforms, and other accounts to make it easy to find and reference accounts.

I currently put that in Business Profile under "Friendly Business Name" since that's what I can search in the dropdown.

The problem is that clients keep changing that, and there's no way to stop them.

I simply want another field, "Internal Business Name", right next to "Friendly" and "Legal" Business name, that takes precedence in the dropdown over the other two, that client accounts cannot edit.
