How to move points from control polygon?

[Pierrafee (Pierre)]

Hello,
I would like to move vertices with different values of my Subd with grasshopper.
How can I do? I have to extract the control polygon from my subd, edit points with value then rebuild my subd from mesh?
How can I select point and edit?

Thanks

Here’re some possible ways, but not that intuitive when compares to you doing the same in rhino.
