For Loop with Feedback --Accumulating Values?

[Justin K]

Hello all, 

 I am trying to grow a selection on a geo group with each loop iteration.  I am using a feedback loop rather than a merge each iteration method because I dont want the geo itself to be accumulated, just the values within the groups.   Any help with this?  If you turn on single pass in the scene file, you can see the point groups I am trying to create on a per loop basis.   Id like to have one group or one attribute made up of all these values once the loop iterations are finished, if possible.  

 

Ive attached a scene file. 

 

Thanks!

EDIT: 

I figured out a way to do this:

I you generate the group prior to the loop

the iterations will merge with each pass .
