Copper Golem Verticality Suggestion

I noticed that copper golems are able to detect chests up to 8 blocks vertically, but can only reach chests a block above them. I understand this is for situations where they can still path to higher chests, but it feels like it could be a bit limiting in storage design beyond the existing range limit. Which the range limit is great for incentivizing people towards more complex sorting when the time comes, but the vertical limit is kind of lame. I think one way to help solve this while also giving more personality is that a copper golem that wants to reach a chest higher then normal could call over other golems in range, and they could make a golem stack to help the golem reach the chest. while this would slow down sorting speed it wouldn't outright punish players for using vertical space with golems. and also cute.
