Nested output destination menus

Here's something that would be a time-saver for me: nested output menus. Currently when I select an output destination for a send or a track I have to scroll through a giant list of hardware outputs, then busses, and finally plugin sidechain inputs. It would be really nice to (perhaps optionally) have those inputs categorized in submenus. So when you, for example, click the output field at the bottom of a track in Console view, you'd be presented with three sub-menus, hardware outputs, busses, and plugin sidechains. That way you don't have to scroll through a ton of bus destinations to get to sidechains, or in my case, scroll through 48 channels of Audio I/O to get to a reverb bus.
