Exporting Particle Position within a 3D Neighbor Grid

Hello!
So We have an emitter that is spewing out all these particles onto a neighbor grid. This Neighbor Grid basically marks particles that are within the bounds as Green and the others as Red. What we want to know is how to export the position of each particle into a blueprint so that we can then print the furthest most particles onto our UI. We have the particle position being read, but we need them only to be read within the bounds of the grid, how do we do that?
