Load all items from queue

Hello
I´ve many different items in a queue. I want to take them all and move them to another position. I want to catch them all at once, but I don´t want to put a load for each item, but I want to make a sub flow.
I attach an example where you want to transport the items from queue1 to queue2.

I don´t know what I have to put in the item tab of the Load activity, and how to manage the sub flow of the unload.

Easiest would be to activate the "Run Tokens One at a Time" in the "Run Sub Flow" activity and simply load the first item in the queue each time. Since you run the sub flow once per item in the queue there will always be a "first" item. The "Run Tokens One at a Time" option will make sure there are no timing conflicts between the tokens, where two or more tokens might want to pick the first item at the same time.

To unload them again, you similarly run the subflow once per item in the operator and have him unload the last item each time (so the items are unloaded in LIFO order).
