When using the surface with a wedge out or IEM out for your PAFL bus, it would be nice if the outputs would follow the current PAFL being used by the surface. For example, you may have different external inputs setup for each PAFL (like one with comms/talkbacks and one without) and being able to use the soft keys to switch between the Surface PAFL would be great. Currently, it seems that switching between the two only switches the headphone outputs on the front of the console, I want it to (or at least have the option to) switch both the IEM output and the Wedge output options.
I could see this being useful for a monitor engineer as well where you may want the ability to very quickly turn off a com channel that is set as an external input for your PAFL.
