Using the ipad with ur44c

Hi all, hope someone can help with my query.

I want to know if I use the ipad pro with the ur44c will it output multiple channels.
This is my scenario
I have audio tracks that have multiple channels, 1+2 are stereo, 3 is click.
Is it possible to have channels 1+2 output to 1+2 on the interface but have 1+2 and 3 mixed to one of the headphone mixes?

I haven’t bought the inteface yet, am holding off until someone can answer this question. Yet the app dspMixFx UR-C doesn’t indicate wether this is possible or not as it only shows 1 slider for DAW.
Once the UR44C is connected would extra DAW sliders show up?

I look forward to a reply
