stairs that curve around open deck

[STACmama 0]

Looking for help (home designer pro 2015) to build stairs like this.  I have the open deck front with the curve, but can't seem to get the stairs to follow the line of the curve around.The options I've found seem to be either a line of straight treads that are curved on the edges, or treads which curve around a pivot point.  Any tips?
