Commercial skip not scanning imported "TV Shows" library

Some more findings - ComSkip seems to only work for shows actively recorded by Plex, and to which Plex is aware that it recorded. I had a bunch of TV shows/movies which were recorded by Plex and had proper ComSkipping. I moved those to another media folder (outside of Plex) but were still mapped to the appropriate media shares. They lost their ComSkip ability even after rescanning them. So it seems that ComSkip only works on media recorded by Plex, to which it is aware that it recorded itself.

Is there a way to use commercial skipping on ALL media, regardless of where it originated from?
