As the photo show,
after product go to the processor from each queue, it will be sent to the other three queue by percentage,
and I want to set a lower bound and upper bound that I can let the queue that its products excess upper bound throw product to the queue that its products are below lower bound.
so I want to set dispatcher to solve this event, only when one queue need to throw product to another queue, and I want to "use transport" only when this event happen,
but when I select "use transport", queue to queue and queue to processor both have operators transport, I just want operators transport only when queue to queue.
