after mining out an area, or chopping a bunch of trees, un-designating an area, or mass-ordering thread(or anything else) from a trader, there can be 100’s items needing to go from the same general area, to the same general destination.
There is already a mechanism for multiple blocks to be carried by a person.
Would it be possible to have a hauler trade, with a tool of a wheelbarrow, which would carry many (16? 32?) items in a single hit, but only deliver items to stockpiles; the hauler specilization would pick a stockpile, then run around and pick up all items destined for that stockpile and drop them off.
This ties into my other suggestions, relating to stockpiles sending items to each other, for establishing logistics chains over extended distances.
