UR28M software reutrn


The GUI (Graphic User Interface) of dspMixFx has only one DAW fader.
Does dspMixFx support one DAW output only ?
How many DAW outputs (software return) can be used to create different mixes?
Does UR28M support the Cue Mixes that allow me to send audio coming into the UR28M mixer to different mono or stereo outputs, these can be inputs from the preamps, but also the audio coming back from DAW or computer?

Please advise me,
Best regards,
