Control Room, "audition" audio goes to only 1 bus?

You can either have “audition” audio go to the monitor bus in control room, or to the phones bus (if you’ve set up one)… but not both…

(Audition audio is what you hear when clicking on individual VariAudio notes… or during real-time mixdown…)

There is an option in preferences where you can tick which output you want.
Why not just have it go wherever you hear your main audio?
