Sweep 2 Rail | Deconstruct Surface

Hello community,

I came across this interesting case. I use the sweep2 component to create a surface using two rail curves and a bunch of section curves. 

What i want to do is to be able to manipulate each of the surfaces created by the every two curves so i can do the divide domain- isotrim combo to create my "panels" on each subsurface. 

Fascinating is that the deconstruct brep does not give me back these surfaces although I can explode the sweeped surface if i bake it in rhino and get them.

I  tried using the split surface with curves command to get these subsurfaces but the results come back as trimmed surfaces which is something that I want to avoid since they carry information of the "mother" surface and I can not control the panel subdivision.

Any ideas?

Thank you all,

Georios
