Can the order locally flag under Agreement controls made mandatory?

Summary: The Business requirement our Client has is that one Agreement created in X Procurement BU should be available to be used for other Procurement BUs. Along with this we also have the requirement that when this Agreement created in X BU, is used by a PO in Y BU, the Procurement BU reflecting on the PO should be Y, not X. This can be achieved using the Agreement controls, where we tick the Order Locally field, for each row added for other BUs apart from X.

Content (please ensure you mask any confidential information): We were not able to achieve this using the personalization, because even after adding the value as 'true' for the Order Locally field, when a new BU is added under Agreement controls, the Order Locally flag is reset to Blank.
