prevent users from using certain account segment values during manual invoice creation

Summary:

We need to prevent users from using certain account segment values during manual invoice creation These segment values represent control accounts, and should not be used manually.

Use Case:

•    Account Segment: Natural Account

•    Restricted Values: 120101, 199999, etc.

•    Expected Behavior: Show error message like:

“You cannot use control account 120101 in this transaction.”

Is it possible to implement this validation using Page Composer, or is there any workaround?
