Prompt User to select a customer location

Client wants the user to be forced to select a location rather than have it default into the sales order after selecting the customer.

Acumatica forces the selection of a “primary” location which will default into the sales order screen.

This field is required so it cannot be “blanked out.”

Was wondering if we might be able to create a workflow that would automatically open the location lookup window after the customer has been selected and the default location fills in.

Any other suggestions would be great, just brainstorming here.
