I would like to bring this up again! A multi-select/temporary gang feature would be a great workflow enhancement in lots of situations, from setup of many lav channels to working with multiple instances of the same source like orchestras and choirs.
In my mind the easiest way to achieve this would be to hold down a select button and then press a second button to get a range of channels or individual select buttons for selecting individual channels not depending on their location on the surface. Then a single press on any select button will disengage the gang. The feature could be enabled or disabled in the surface settings and that setting could, but not necessarily, be assigned to a soft key (like the DCA spill setting for example).
