Cubasis Output Select

[mec]

How can I route the stereo out of the mixer to another output device? When I use an interface (Focusrite iTrack Solo) it does automatically. I do also use a Bluetooth audio connection to a monitoring system. That works fine with all apps except cubasis. Sound only comes from the integrated speakers. How can I select the output?
Thank you folks.

Now I have response from Steinberg support team. Mr Nedderman so so kind to tell me that this function is not implemented yet.

Thank you Mr Neddermann!
