I've noticed that when I turn in a collection of items, the item displayed in the medallion happens to be the last item I have obtained for that particular set. I know that multiple accounts is now against the rules, but I was wondering if I could just trade an item over to another account and then back again so I can have the item I want displayed on my medallion. This does not give me any in-game advantage unless you consider "choosing" the item to be displayed on the medallions to be cheating/exploiting. Get back to me, thanks.
P.S. Maybe in the future a way to choose the item displayed for yourself?
