Quirky Stairs

[FernaldBuilding]

I'm trying to recreate a set of stairs in Chief. See attached. Is there an easy way to do this? with focus on the bottom three steps. I tried doing a straight stair sandwiched by two winders which does the top winder section nicely but leaves a lot to be desired on the bottom section. My gut tells me to create three stacked soffits in my desired shapes for the bottom three steps followed by the straight stair and then the top winders (if possible). Not sure if there is an easier way. The shape, size and orientation of those bottom steps tells me probably not.

 

FWIW I'm new to chief architect but have been using home designer for a few years.
