PS4 Can You Paint Specific Parts Of The Train In Tsw 4 Livery Designer?

I’m currently trying to make a custom livery that would require 2 different paint colors be present on the body. More specifically, only the doors need to be a separate color. I haven’t been able to find a way to do this. If there is, can anyone help me?

 

Paint the main body the main colour use a shape (you can resize the shapes) to colour the doors a different colour.
