Villager seem to prioritize picking up materials from the closest location possible. While this is often a good idea, it becomes incredibly inefficient when large amounts of materials and only small stacks are close by.
Examples:
-Trading post guy stocking up on 500 wooden planks keeps picking up the production of the sawmill (2) instead of visiting the full stockyard that is right behind it.
-Builder picks up 1 stone from a workcamp instead of walking a bit further to grab a pile from the stockyard
Since transit is quite slow in Farthest Frontier, getting something built far away on a big map is already quite difficult. Having them bringing the items one by one on top is quite frustrating from time to time.
Note: This request would be obsolete if villagers would be able to pick up material from multiple sources in one trip until they have the desired amount or are full. This would be even better.
