Is there a way to create "webbed" lines when they intersect?

I'm looking for a way to create "webbing" on two intersecting lines. What i mean by this is that when you normally intersect lines, they form sharp angles at the intersecting point. What i'd like is for the lines to have a nice smooth curve when they intersect. See attached picture. I currently have to do this manually and it takes a long time. Is there any way to do this now in fresco?
