I guess the problem with the new stairs is they are just a symbolic line representation in plan because you have the visible and hidden portions with the break line in between.
That is why you have the fill settings in the grid display settings.
It could get a bit tricky to use the tread material as there sometimes will be no tread finish and potentially each tread cold be a different material or even a custom tread with many finishes.
This might get even trickier around the break line if there are different materials.
