Set pick-up date/time in Register check-out

I did not really find a good tag to put this question, I hope somebody reads these questions.

We use a Square Register in our business. Frequently customers call in and order goods to pick up later in the day or on another day.
Is there a way to set a pick-up date/time before payment or save ticket?

The idea would be to retrieve this information on a separate system using the orders API.

Thank you.

I’m not aware of a way to do this directly in the POS. If you create the orders via the Orders API, you can use the fulfillments field which has details such as pick up times, and you can push it to the POS by paying for it on the API.
