Subdivide column point domains into groups according to attractor / Tree Managment

Hi, I would like to divide point columns with one attractor point for each column into subgroups. So my result should be controllable domains of affected points.

For one single column everything works fine.
But when I try to do it for all columns with each individual attractor point it is not working. I do not have that much experience with data trees, so hopefully someone can help me.

Thanks a lot for your time! (516.4 KB)

Can anyone help me with this?
