Dumping Stockpiles, make loose item higher priorty over already stockpiled item

[BoogieMan]

Specifically for chunk hauling, I usually have a higher priority rock chunk stockpile near the sculpting stonecutter workshops that is moderate in size, with much larger stockpiles out of the way for all the excess chunks.

The problem is, haulers will waste time taking from lower priority dumping stockpiles to this higher priority one when a spot on the floor opens up all the while ignoring chunks that are not in a stockpile even when they are actually significantly closer.

So I would like to suggest that an improvement be made to the function to increase the priority of items selected for hauling that are not currently in a stockpile over those already stockpiled. At least specifically for Dumping Stockpiles, and maybe not regular Stockpiles. I do like them taking from lower ones when the higher one runs low to keep the items close at hand, but not over items just laying on the ground.
