Most of my scenes and environments have an atom called autofocus point already set up with postmagic as a plugin on that atom. If you save presets of them you can easily load in other scenes with it already set up.
This is an old tutorial vid I made on how to set it up. I no longer use postmagic in the scenes plugin tab and put it on the autofocuspoint itself as it makes it easier to save out and load up different lut presets but, the process of setting up the near and far focus is the same.
