I can see the usefulness of this. I have four rooms where I would want tablets installed to host dashboards. All would have some items in common, each would have some items unique to that room. I don't have so many "things" that it would be overbearing to create each from scratch, but it would be easier if I could have a common container (Tileset) that only has to be edited at one place to take effect on all dashboards.
