Copper Golem needs to be able to sort different types of items in one chest

The Copper Golem is almost perfect. Almost. See, it does alright with sorting items in the chests, however, it needs its capabilities tweaked a bit. Let me explain. I did an experiment where I had two regular chests. One for wood logs and the other for wooden planks. And so I made a copper golem and in the copper chest I placed some Pale logs, pale planks, cherry blossom logs and cherry blossom planks. The Copper Golem will then take these items and put them all in the right chests right? Wrong. It would take the Pale logs, put them in one chest, then take the cherry blossom logs and put them in the other chest. It does not matter if the items are of similar type, name, or function to the Copper Golem. They are not the exact same item and thus only one chest is reserved for each specific item and not its various forms. Now you are probably thinking I could just put the items in myself for the Copper Golem to recognize and put more in, but then what would be the point because by then I would just sort them myself without needing the Golem. So please fix the Copper Golem so that it can put an item and it's various types in one chest please.
