Creating spline blueprint with several mesh varitaion

I am beginner to blueprints and trying create a sidewalk spline with several mesh pieces instead of one. However i couldn’t find out how to add and randomize more mesh components to my blueprint.

The blueprint works well with just 1 mesh : spline posted by anonymous | blueprintUE | PasteBin For Unreal Engine 4
