Prioritize trucks

It is vital to have a possibility to forbid trucks from taking certain recourses onboard, otherwise, haul trucks are totally useless. Because it is very unsatisfying to see it leave the mine with 2 units of dirt and travel many km to dump it, especially when there are other vehicles on the premises

Under the Vehicles tab on the main screen, there is a toggle to force trucks to wait until they are full.

Thank you. but it will only cause haul truck to stay a VERY long time if there is not enough dirt to fill it...
