Keyboard View Instrument Selection

When using multis, we should have more control over which instrument is displayed in the keyboard viewer. Right now, the only to change that is by clicking on the instrument header (even that is somewhat clumsy as there isn’t any definite space to click on). It would be really nice to have a way to select that through multi scripts, keyboard shortcuts, or even an option that automatically selects whichever instrument is receiving MIDI. I know banks were designed to that, but the fact that one can’t see the performance view makes them totally useless.
