Finish/treads of the stairs to not show when selecting "without finishes".

[Leire Bilbao]

When doing a concrete structural section for example, if you click the option "without finishes" the floors and plasters and other layers hide, but the tread finishes on your stair stay. It should be consistent and behave as a floor finish.

Currently I need to do 2 stairs, one for the concrete and one for the finish, or draw / cover with fills which is bad

I think it is a pretty important missing feature. We need the stair structure (concrete, steel, etc.) to show in certain views without the stair finish parts.
