Sorry, I think you guys misunderstand me. My fault for using the term 'reference' possibly incorrectly

I want to be able to tell which new Falmer in game corresponds to which one in the CK for instance. So, I mean like, if I hit ~ in-game and select a new Falmer, 0005f62c. How do I identify which new Falmer this is in the mod in the CK, so I might remove it from levelled lists?
This is what I figured, something to do with BSAs. If what SluckyD said was correct, I'd expect the asset not to load in-game either, right?
