Is it possible to create a mixed Fulfillment for single order using Square API. For example if I wanted to transact two items on behalf of a merchant and one of the items was a normal food item that needed to go to kitchen/printer, and the other item was something that didn’t need to (second item is an ad hoc item) how could i used fulfillment entries to make sure only the first item went to kitchen and the second was ignored by typical fulfillment routing (not through item categorization). Is this possible within the API?

At this time the only way to control where the order is printed is with the categories. 
I understand that categories can be used to control where the order is printed, but is there another way to control what items even go through the fulfillment pipeline?
