Make 3D GUI box yellow if given “line up and wait” command#45

Basically what the title says. A plane taxiing to the runway has a red box with the runway number in the 3D GUI, once given takeoff clearance it turns green. Please have it turn yellow once given “line up and wait” command. Also in a similar vein, maybe the box is just grey after pushback instructions, and only turns red once you give it taxi instructions? Basically use more colors to indicate aircraft state
