The solution could be some kind of mine cart. A little train with a pumping motion made by one or two players to operate in a chosen direction following rails and special ramp with rail, set on the floor, the other wagon are considered by the game as kind of stockpile.
Could be manual interactivity, produced by an other job, tier system with materials (wood, iron, steel). To me, it seems a bit complicated to implement, like a big update. But in the spirit of the game, useful for every job, and i'm pretty sure most of the players would love it.
There's a suggestion people can vote on for that as well: https://eco.canny.io/feature-suggestions/p/minecarts
