Missing infolabel?



https://kodi.wiki/view/InfoLabels

Is there a missing value for “source”. In Media Companion, source is to select “bluray”, “DVD”, “WEBDL” etc.

In my media flag retooling, I realized that I can’t depend on filename as most will not have the strings based on naming and must revert to the actual tags of the file. All of my files (I’m a rigid tagger) has the source and WEBDL is needed to enable to the flag because it does not exist in the filename. 

So is this a missing infolabel since source seems to be part of all of the taggers out there and not an obscure tag. It is either late and I’m missing it, or I’m just missing it…. is it really missing?

Thanks.
