Identify non ComicTagger tags

I would like to request some way to identify comics which have tags whose tags were not made with ComicTagger (and may even be completely blank)

I would prefer this to be a native GUI and command line feature rather than some non CT hack.

Do you have an example the sorts of tags you're talking about?

The CBI standard does allow for customs tags, and I suppose the CR ComicInfo.xml format could also accommodate custom fields too.

When you say identify, do you mean just display, or allow for editing too? In either case, I suppose there would have to be (in the GUI) a new tab with a generic table of name/value pairs. Of course if there are complex data types this become tricky. No matter what, sounds like a good bit of work.
