Customer selection restriction on Order Management

Hi Team,

Greetings!

While creating a sales order, the User wants to restrict the customer selection from a List of values. Is this Possible?

Note: When the customer is entered in the Sales order level, the system displays results from all business units because it is selecting at the Organization level, which is Global. In instances where the same customer exists on multiple BUs, it is confusing for the Business user to select the correct one. Can we think of any way we can restrict access in this search to the user's own business unit-linked customers? Or possibly to additionally display the linked Business Unit in a search (bearing in mind the link happens on the customer address set level)?
