Group Sales - Configuration of limits to disallow higher quantities for pre-requests per STG

Currently, on the Group Sales portal, after the Box Office operator has created a pre-request, users can either submit the pre-requests without any modifications or edit them to add or remove tickets proposed by the pre-request allocation. Due to contractual distribution of tickets for some clients, we are now introducing the possibility to control the limit of exceeding pre-requested tickets at the Sub-Target Group level so that pre-requested allocation can only be exceeded by STGs who are authorized to do so.
