Finding a scorer to determine angles of particles

I am currently using a primitive scorer to determin the number of neutrons in cubic volumes. Which works fine.

The second quantity I am interessted in is the average angle of my neutrons in each volume (relative to the closest axis).
Is there a scorer than can give me either all of the angles for each volume or even better just the average one of each?

Currently I am determening these quantities using the stepping action which is way more complicated and computing time intensive than i hoped this would be.
