Hello I am doing a multistory stair in revit which has 4 flight, I need to create railing (not continuous) from first flight to landing and second flight to landing which I was able to select by "pick new host" (the whole stair was selected ) and the railings are in right position the problem is when I need to create the 3rd and 4th railing which when creating falls on first flight and I am not able to select the particular flight using "pick new host" since multistory stair is like a group of component which you cant explode - when using "pick new host" It will only select the whole stairs and the position of handrail will fall on the first flight just like I did on the first and second flight..
