As I mentioned in my orignal post, its when I create an outfit. I make clothing and sell it in game, so when I box the items I only want to sell what I made, and I don't want to include everything else (shoes, hair, face light etc). When I use to use the phoenix viewer, I just use to click the "make outfit" in the appearance mode, click my items and it would create the folder. I figured it could be done in Viewer 3 but so far I haven't found the solution.
