How to Split a single divided contours list into separate branches for toolpath generation

Hi, I am attempting to take a list of points from 6 subdivided contour lines taken from 8 individual notches in the rhino geometry to be used for toolpath generation in kuka prc and essentially try to select each point group in each notch indivdually. This is to be able to organize the notch point lists to be milled in a specific order and to reflect that in the toolpath of the robot. My issue is with the data organization aspect of this, seems tricky for me.

Thanks
