Alternatives to Make PO Number Search Field Mandatory in Billing → Manage Transactions

Summary:

Making PO Number mandatory in the search section of Billing → Manage Transactions when Page Composer edit is disabled.

Content (please ensure you mask any confidential information):

I’m trying to make the PO Number field mandatory in the search section of the Billing → Manage Transactions page. The Edit Component option in Page Composer is greyed out, indicating that the field is part of a seeded page and cannot be modified directly.

Since Page Composer doesn’t support this change, I’m looking for alternative approaches (like Application Composer, personalization, or another configuration method) to enforce the field as mandatory.
