Works on any storage building block. The regular interact prompt will pop up and show an ADDITIONAL line to mark as dump. And will change the name of the chest to <player's name> dump <invetory item>.
Anything inside this box will fan out to anything inside the base range that has a matching item from closest to farthest. Non-matching items will stay in the box.
Works on dedicated servers. PLEASE let me know if you have any issues.
