Using particles.blob accurately

I am currently running a local refinement job using 2x binned particles, which were preceded by symmetry expansion and follow up 3D classification. I combined the best 2 classes for the local refinement. I want to run a followup local refinement using the same particle stack but unbinned, and I have run an extraction job with no binning. My questions is - how do I run this local refinement without having to do 3D classification again? I could symmetry expand the unbinned particles, but I only want a subset of them to feed into my final local refinement (corresponding to the best classes from my 3D classification on the binned particles). Would using the particles.blob output from my 2nd symmetry expansion (unbinned particles) and adding that that to my new local refinement (using the first local refinement particle stack as input) work to achieve this? Thanks in advance!
