I think that is a great limit of all the addons for stairs' making ...
I'm writing a custom stair with these options ... let me complete it and I will share it ... it's in Italian but I hope to have the time to translate it ...
It is derived from the will to draw in archicad also the structural drawings (it's a big challenge without a specific addon ... and I don't know anything about the SDK and the C++ ...)
This stair is derived from a common way of building and allows the user to show also the raisers and the treads or the structure only and moreover allow the user to define the section fills for raisers and treads ...
