This is something that is available on Subeta 2.0 sites (like the Wardrobe and Custom Wearable-related pages). I believe it will continue to be available on all 2.0 pages, and therefor eventually site wide. It won't be added to the current non-2.0 pages because we are concentrating on getting pages set up on 2.0 rather than adding new features to the old, outdated code :) I hope this helps!

Locking this as there is an official answer.
