Set of images as a cover

As partly mentioned in Image (cover / normal) support for online library (like unsplash) and referenced in Layout as a Type with templates I would like more options for the cover. Not just having one image, by uploading or selecting from an online repository such as unsplash, but also a set of images from your AnyType or a category from f.e. Unsplash with configurable transitions and controls. And this slideshow object could be usable on the canvas as well.
