I use two resource, one is for pallet, and the other is for box,
I give every box a label name "destination" means where the box will go, but the pallet not,
the combiner mode I choose "Pack", when a box and a pallet go to combiner, box is packed,
my question is how can I set the flow of the port that it can send the box packed on pallet to the destination by box's label "destination".
