After the Diesel legends pack, i got frustrated that in timetable i could only select the enginge livery on the class 52 and not the coaches, wich is anoing together with multiunits where it only puts livery on the front unit (Class 101, Talent and so on) Maybe it could be an idea to paint locomotives with their wagons like it is on the ICE, Talent and so on. An examble could be that the Class 52 is shown with 1 of each wagons, so im sure the different layers are located in the same area on each unit (example stripes and roof)
