Adding ‘Documentaries’ to menu next to ‘Movies’ and ‘TV Shows’

Not sure if this is the right area for this question (i.e. not sure if this is related to Confluence or to more fundamental parts of Kodi) but here goes.

I have a large number of documentaries that I would like to have available as a separate menu option. Out of the box there’s ‘Videos”, ‘Movies’ and ‘TV shows’ and I would like to have ‘Documentaries’ in there as well.

Right now documentaries are treated as TV shows. I don’t like that.

In fact I’m not wild about the ‘Videos’ menu option next to ‘Movies’ and ‘TV shows’ (both of which are essentially videos) but I suppose I’m stuck with that because without it I can’t add new items to the library, as far as I know.

Is this possible without major surgery? If so, how?

Tnx in advance! All hints and pointers in the right direction are appreciated.
