Shrink and Divide patch surface?

Grasshopper

Hello !

I am trying to create a framework of a parametric surface which has been created with patch command.
However when i divide the surface it devides all the untrimmed surface. How can i divide only the trimmed surface?

You cant.

And if you want to understand why: Rhino - What are NURBS?

So there isn`t any solution in my case?

Thank you. However just out of curiosity is there any way to trim a surface with an extrusion in grasshopper. Cause I haven`t found a way yet.
