Can I download a rented movie to Apple TV 4 for later viewing?

I want to load up a couple movies on to my Apple TV prior to traveling so I can watch them on the road (rather than rely on hotel WiFi bandwidth issues to stream as I watch).

How does this work? If I rent a movie through AppleTV what actually kicks off the download to the device? When I purchase the rental, or do I need to start playing it?

Basically I want to download a few movies that I can watch at a later date right on the AppleTV without having to rely on streaming or downloading over a slow WiFi network.

I've tried downloading to my computer and playing via AirPlay on ATV in the past, but again, relying on hotel WiFi for even that has not been working.

Ive done numerous searches and I can't find any clear cut answers on if/how the AppleTV actually STORES download/rented movies.
