OK, but let's explain to people what this means in practicality (apart from the delay issue). Since a Lutron scene can contain every single light in the system, one command coming from the control system can in fact adjust every light in the house. So the only time the limitation you mention would be an issue is if someone wants to select multiple lights or scenes one by one to create an "on the fly group/scene" so to speak, and then raise or lower that group/group scene. I've never even once had anyone ask me to be able to do that, and personally it's not something even I as an uber geek have the slightest in interest in doing (now is when you tell me how all your customers cannot live without it
And to clarify for people, the above limitation does not in any way stop someone from raising or lowering every single light in the house simultaneously, or any scene for that matter. It just means the system won't allow ad hoc grouping of lights and scenes and then raising and lowering that ad hoc group.
The second issue you mention that I did not quote is significant and obviously needs to be fixed with a firmware upgrade.
