You will definitely find SLABS and WALLS a better solution!... Railings will be sketchy, but using the different stand alone railings that come with AC should suffice (or create them yourself w/ TUBES and PICKETS)..
Slab your treads just as you've already drawn them. One trick I like to use is
1. draw your first tread with top at 0' 0" (match low floor level)
2. multiply by DISTRIBUTE -1 with number of stairs and FLR to FLR offset
3. Option click to transfer these heights to the actual stair treads that match your plan...
Let me know if I didn't explain that well...
THEN... if there is no UNDER STAIR SPACE, simply use a SLAB as the BODY of the stair structure and SEO the treads with UPWARD EXTRUSION. You can specify the linetype of the structure slab as hidden and add the hidden lines for the nosing line as shown in your drawing..
