Agreed! I was just searching this subject. I don't want to change a bunch of other peoples racks just because I want the non-standard knobs on my module to be represented in my ModularGrid rack. I "could" create a separate hidden module but it seems a waste of time and server space. hmmm, maybe I'll upload my panel version, and then right away upload a copy of the current panel version?
Maybe a check box next to the panel image upload button the is labeled "Make This Image The Default?" or a popup prompt etc would be good?
