Is it possible to bend decals and make them follow a slope?

As some of you may have seen, I'm trying to build my own custom roads with customs marking. For that I use decals that I place on the roads with Procedural Objects.

I reached a point where I have to place my decals on curves and slopes, and since it doesn't seem to be possible in the game I searched on Google but I didn't find anything that helped me.

So I'm asking the question : does something exist that can bend my decal as you can see on the first picture and something that can make them follow the slope on the second pictures? Or is it just not possible at the moment or never will?

The pictures are here

Thank you so much for your help.
