Mono output for the mix, Stereo for headphone cue

I’m not sure why this option was removed, but many people find it’s very important to allow an option to output the mix in dual mono. This is for people with full featured DJ controllers, no need for a split mono splitter. Give us L/R “stereo” output with both Left and Right channels consisting of identical mono signals.

I need it too!!! Its very important to mix via mono.

Is there any update?
Its so important!
