Virtual contact sensor for SmartTiles?

My thought is to have a single tile on SmartTiles that is a virtual contact sensor which groups ALL contact sensors, but represents an “All Closed” or “somethings open” visual affect.

Ive created the virtual contact sensor, but am having trouble finding an app that I can either repurpose or use, for this type of setup.

Thoughts? Should this be in the Smart App recommendations?

Instead of a virtual contact sensor. You could use a virtual switch and use Smart lighting apps to tie them together. You can then display this switch in smarttiles.
