Per-particle CTF refinement

First of all V2.2 is really great. The (fixed) non-uniform refinement works really well for me now (btw is there somewhere with a description of what it actually does? I couldn’t find one).
I wanted to know if there are any plans of implementing per-particle CTF refinement in the future. Currently if I want to do this I have to switch back and forth between relion and cryosparc. Is that necessary or am I missing something obvious and there’s a way around it?

You can use Relion’s ‘Display’ feature within the Relion GUI to select particles that below to a certain class after 3D classification finishes. This would be useful if you had only one or two classes after 3D classification that were homogenous and warranted further refinement.
