Adjust superelevation/cross slope transition on intersection

In attached file the normal cross slope of secondary road(AB)  is 2% Right to left (Right higher). and for primary road cross slope is 2% Left to Right (Left higher). I produced this junction using intersection wizard and cross slope of secondary road only starts changing from start of curb return to match the long slope of primary road. Is this possible to increase this transition lentgh on secondary road to create smooth contours.

 

any help will be a sigh of relief for me ....

Choose All Crowns Maintained for intersection type; use a Widening.
