I have to assume it must be possible to automate "storage module assignment" for items that flow into your unassigned bucket, since so many computationally tricky things are possible already.

Its just, I assume, a case of whether it is worth doing instead of manually assigning a new module for any new items added in updates.

On a tangent, I sort of appreciate the fact that a lot of this automation stuff isn't an inherent function of the game, they give you very low level components and you build the logic yourself. It makes those monumental technical Minecraft builds such a cool vibe. If things like filtering were more trivialised I think a lot of the magic might be lost
