Be able to cycle through the idle trucks

Having a way to cycle through just the trucks that are idle to be able to spot where you have a slowdown in mining or where your trucks are sitting full of resources and need a point to drop it off. Also having the mining towers show in real time how many trucks or excavators are idle when looking at their overview screen when you click on them. It could be as simple as when looking at each mining tower screen, it has an icon next to which vehicles are idle so you can jump to them specifically.
