I mentioned that to the wife, she said no! She mentioned that it only takes about 5 minutes to switch over to roto, which is true.
Also I have the CB rotisserie for my 22.5 kettle or WSM so if I need to good something while using the roto I could do it on the gasser with the roto on the kettle.
But it would be nice. Too Bad that Weber makes there stuff so well, I will never get a new grill!
