Thanks, this is an interesting suggestion. I think it's related to the need for a transpose supercontrol in MIDI Designer (this is a very unique case of transpose, which has rules on hiding and not hiding)... for right now, it's not possible, but it's possible to think about including some kind of logic like this in MIDI Designer in the future. This has been added to the suggestions list but no promises as to when this is going to happen. Adding programmability of this type in MIDI Designer is awesome, but it has to be done right (because once you have layouts created with a particular feature, there's no going back).
Thanks!
