help with surface in rhino

I'm new to Rhino and a bit lost at what's probably a very simple problem. I've been looked for a couple of hours now, and figure I might better ask some more advanced users.

I am trying to make a surface between two curves, but that has to go though 2 "cross section curves" (one in V and one in U direction). I use "Surface>Edge Curves" to make a surface between the two curves. Next thing I want to do is to have lines of control points in the centre in U and V direction - 1 and 2 - that match the "cross section curves" - named A and B - exactly. I cant figure out how to do this.

I tried to use InsertKnot to add a row of control points in the V direction, without altering the shape. (If I use InsertControlPoints, then the surface edges don't match the original outer curves.) After InsertKnot, I move the control points of the surface to the controlpoints of the curves. But then the surface isn't smooth like I want it.

I tried NetworkSrf, but this is not so precise? Also Patch, but I mean, there must be a simple solution in the fist method, no? Your help is appreciated!
