I have a model with two processors. Two different types of items are processed with one processor and two different types of items are processed with the other processor. I would like an operator to be involved with the setup and processing of processor 1 and transport the two different item types to there respective packing area. Then go back to processor 2 and setup and process the two different item types and pack them in there respective packing area. How would I do that with the current model I have?
