I want to make a list of tasks for a transporter in warehouse. The warehouse contains 50 racks, and there's an SKU on each rack. I wanted to give the transporter a sequence of tasks to be done. For example, I want transporter to take itemType 4 then itemType 28 and itemType 14 then move them to the queue. Then take itemtype 19 and itemType 47 the deliver them to the queue.
