I am fairly new to blender and I am starting to use the geometry nodes. Currently I am asking myself if there is a way to subdivide the surface of a cube unevenly. What I mean by that is more easily explained in this image then explaining it by text: 
I believe this has to be done with moving the centerpoint of every face in two steps:
- move center point of all faces in a row
- move center point of all faces in a collum
- subdivide
This way I would keep the structure that I want in the xy-plane and not have randomly displaced n-gons. Is this possible by using geometry nodes?
