Soundcard and DDJ 200

I’d really like to get decent stereo output and cue without the need for a mono splitter cable with my DDJ200 and iPhone…
Is it possible that I could use something like a Reloop Play DJ USB Audio Interface (or it’s replacement the IPhono2) connected to my iPhone then out to my speakers and still get a cue line for each channel from the Reloop Device connected to headphones?
Thank you!
