Transport default

Trucks of all sizes will have a setup to ONLY haul a Selected Product or Commodity (e.g. Coal, Iron Ore, Lumber, etc.)

I'd love to see the ability for players to set exclusions for materials on certain trucks assigned to mining operations.
I've had many times where one of the haul trucks carries 3 dirt across the map to my dumping site.
I'd like to keep the bigger trucks for only transporting the mined material to storage and use smaller trucks for the materials to be dumped.
I can work around it by setting up a close-by dumping site and re-mining said dumping site, but managing this can feel a bit tedious at times.
