Locate the contact from the address book. Once you have found the contact info click on the drop-down arrow next to the edit button. You will see the options "New Shipment To" and "New Shipment From".
Select your preferred option and the page will redirect you over to the Ship page to complete your shipment.
You can also use the checkbox to select individual people or multiple people at the same time. Use the 3 dots to select "Ship to selection". This will add the order to the Batch page to process those shipments on the Batch page or the Ship tab. For more details visit the Help Center Article: How to Add an Order to a Batch Manually
