You should be able to use print-item-hashes, search for repetitive hashes (weapons, armor, tatoo, ship skins, etc. are all "Quantity: 1), then add that hash manually into table (only one) and you should be able to see multiple different addresses, but with same hash. Remove all, except one.
Save game, exit CheatEngine, load saved game.
Anyway...
I have like 280 unique 1 quantity hashes, so it will take some time to find them all...
