sample refined surface and keep cell order

Hey,

I have a refined mesh after using snappyHexMesh and I want to sample data from a surface of that mesh with one sample each cell.
But the samples are in a different order than the real cell order of the surface.
Is there any way to preserve the right cell order?
This is my surface file:

Code:

  

  type            surfaces;

    libs            ("libsampling.so");



    writeControl    writeTime;



    surfaceFormat   raw;

    fields          ( U);



    interpolationScheme cellPoint;



    surfaces

    (

        surface

        {

            type            cuttingPlane;

            planeType       pointAndNormal;

            pointAndNormalDict

            {

                point   (1 0 0);

                normal  (1 0 0);

            }

            interpolate     false;

        }

    );

thanks

Or , to put the question in a different way: Is it possible with this surfaces file to get an extra column with the cell id number?
