One button to set a common scene in every room defined in Hue?

Unfortunately, I believe the only way that SmartThings has access to the scenes created in the native Hue app is through IFTTT. There is no direct access to them. SmartThings also doesn’t know how the hue bridge defines rooms.

People do create their own scenes in various different ways, including with core, but that isn’t the same thing, I know.
