Add option for multiple outputs from the output rather than having to use the sends.

I typically use 5 main busses, but like to A/B tracks going to different combinations quickly. Rather than having to place these after 8 sends (because you can only edit levels for the first 8 in the faderport 8, so I save these for fx and parallel chains) I'd like an option similar to summing mode in cubase or at least how protools sends to multiple outputs that is separate from the sends.
