When changing ship to location to third party on the order header, bill to location is automatically

Hi,

I'm trying to create a new order for a customer with a third party relationship. The customer should be billed for the order but the items should be sent to the ship to location of the third party. When I'm creating a sales order and enter the customer number the bill to and ship to location are automatically populated on the order header. Then I click on the three dots in the SHIP_TO_ADDRESS2 field to find the address of the third party. The Find Customer Information form opens. Here I enter the name of the third party and click find.
