Does anyone know of a way to create a loft on a set of curves including a hole?

Attached is an image of the curves I'm working with. They are irregular shapes. I've been messing with some of the surface features (mainly loft) for a while and I can't figure out if it's possible to include the hole in a single loft-like operation. Can I select all of the bottom curves as the starting point, then select all of the top curves to be the end point some way? Does a hole basically screw up the boundary conditions and make the solution impossible? I'm using NX 12.

I can loft the outer curve and inner curve separately then subtract the hole, but I'm looking for a more concise solution.

Thanks!
