Support a background color behind dashed (or non-solid) lines
Which area of IMT is your request about? (ex: Lines, Fillers, UI)
Lines
Describe your idea clearly and concisely.
In some cases, I want to be able to draw over top of existing lines, but this is hard when using dashed lines because the length/gap may not match up with the existing lines, so they show through. It would be great to have a "background" color, where the lines drawn will completely cover the existing road lines, even when using dashes.
Screenshots?
Provide a visual if possible what your idea would look like

Hi @brandonscript,
I tried to implement it but, there is issue with lines, they are painting in bad order and straight instead curved. But I have found different solution and filmed here: YouTube 2:03 Note: Line points must be splitted and filler must be connected to line which may be not the under-painted.
Issue of non-curved lines is at the begining of video @MacSergey
I wonder if an easier solution is just to support multiple lines per node-set? You could then z-order them (so the dashed lines would be on top of the solid, road-coloured line)?
I will try to find something in code but, It would be a bit complicated, because of very well made abstraction.
