Can we pay for a Pickup Order in-location using Terminal at time of pickup?

Any changes in the API @Jordan that would support our original request - pushing itemized orders for payment on a terminal device?
I am asking since I saw this in my e-mail today implying that itemized order payment might be possible:

Also snippet from Orders API - Square API Reference implies that it is possible to push itemized orders for payment on a terminal device:

“You can itemize payments using custom line items or catalog objects, send orders to physical Point of Sale devices to be fulfilled, attach a customer to a payment, and more.”

Upon quick inspection of Terminal, Orders and Payment APIs I don’t see anything obvious allowing us to do what the snippet above states: to " send orders to physical Point of Sale devices to be fulfilled"

Can you @Jordan please bring me up to date on the API - am I missing something here, or the documentation ( cited above ) is just not correct.

Thanks,
