Adding additional filtering to /assigned_fulfillment_orders REST endpoint

As of API version 2023-04, you can retrieve a subset of fulfillment orders which are assigned to locations owned by the app performing the request but have not been requested for fulfillment so far.

The assignment_status query parameter in the /assigned_fulfillment_orders.json endpoint can now accept a value of fulfillment_unsubmitted for filtering in addition to the existing fulfillment_requested, fulfillment_accepted, and cancellation_requested filter values.
