How should I flatten the edges of a warped trimmed surface

Grasshopper

I am trying to flatten the edges of a trimmed warped surface. Essentially, all the boundary edges would be z=0. There were some interesting posts about doing this with regular surfaces and the graph mapper but I keep running into issues with this trimmed surface. (divide surface has null points, etc)

What’s a good way to do this?

Finally got it to work. Just out of curiosity, is there an easier/more direct way than this?
(Not criticizing this tried-n-true method from these forums, the control from the graph mapper is great)

As you can see in this example, if you have enough control points to work with near the trimmed edges, you can use Point Deform.
