Can I edit a Shared Scene from the app?

The only way to access a Shared Scene in the iPad/iPhone app seems to be by selecting a button on a keypad which uses the Shared Scene. But when I edit it, it only changes that button on one keypad and unlinks the button from the Shared Scene. The Shared Scene is not changed and all other buttons using that Scene are unchanged.

Is it possible to Live edit a Shared Scene with the app so that it will change everywhere it is used?
