Modification of Varying Shell Thickness on only one side for complex slab?

First time here and really liking the flexibility of Karamba and hope this is in the right spot!

I have come across an issue which has been driving me crazy and am unsure if missing something. I have been able to create a 3d shell (with tris not quads, first hump) with individual heights per face, however the issue is with the dual direction offset. Is it possible to assign the height on only 'one-side'?

I am desiring to use a list of face centers or vertices (preferred) to make complex slab shapes that will NOT be able to be described parametric equations or with repeated symmetrical cross sections (created through Millipede, meshs around 100,000quads/200,000tri). As a workaround to achieve this when pre-canting the mesh to make the double side offset even the top, the resulting mesh side is not planer due to the normal direction. I am also unsure if in the actual the method of analysis this matters? Does each face need two numbers? Is there a specific data arrangement to achieve this? Can I pass two lists, one with all 0 and one with all of the center heights?

NOTE: The attached files are in Rhino 6 and the GH uses a weaver bird component however I have internalized the result so it is not necessary.

NOTE: The example is just an example witch illustrates the problem as having a file with an actual example from millipede goes over the file size limit.

Thanks!
