Upfront themes: same "child-themes" workflow / philosophy?

Hey Superheroes,

Just getting started playing around Upfront. So my question is pretty Dumb and Simple:

Can I create Child-Themes for Upfront Themes? Is it all the way the same procedure + code (in style.css) as "traditionally" done with other themes?

Tried to find some clue in a quick forum browsing, but did not come up with any light on this.

Thanks a lot, have a great w.e.!
