Cast to combine cards from multiple pages

I think that it would be great if you could cast the content of several pages and it just effectively combines the cards from them onto the one page (one after the other).

This way, for example, I could cast an generic overview + the relevent page to the zone that I am casting to:

  "entity_id": "media_player.googlehomehub_kitchen",
  "view_path": "overview,kitchen"
