Storing a storyboard within Storyline

Not a requirement but I am wondering if there is a way we can 'attach' our storyboards to a storyline file, so that they both can live together. My only solution is attaching it as an embedded file to a non-displayed stand alone slide.

Is that the only way or best way? Attaching it as a resource will make it visible to the learner (if there are other items in the resource section), so trying to see if anyone has better suggestions.
