I would like a way to have a conveyor or maybe a new slot type that I could place that would allow me to set rules between cars coming in and those going out. There would be one in feed slot and 3 out going. I could set a rule for every 10 cars coming in 5 go left 3 go straight and 2 go right or whatever I want. This would allow a finer control over car types that are produced. Especially in a mega sized factory.
