Like they said to me, sometimes just searching through google and the documentation is a skill in itself, I found this nice little piece about patrol points for navmesh agents buried away in the Unity documentation fairly recently, had no idea it was there at all, it's obvious once you saw it on the menus but this is the problem with all these hidden menus and so on.

I'd say Maya is far worse though for that kind of thing.
