Generate an order with 2 fulfillment order

My use case: I want to create a Shopify test order with two items [A, B] one of them belonging to L1 and the other to L2:

L1 → A

L2 → B

What I’m doing right now is:

  1. Using the fork support provided me (https://gist.github.com/youmikoh/362ee9e42ef136c855b4ab02f0cdb946) to create a test order with 2 items through Postman. The order gets created with both items in the same location (L1), so it will only have 1 fulfillment order.

  2. I’m using the fulfillment_orders/{id}/move.json endpoint to move only one of them to a different location L2, so I end up having an order with two fulfillment orders:

And I was wondering why it is not possible to create an order directly (‘directly’ meaning in one request) with one item in location 1 and the other in location 2. Somehow this is related to this other post:
