How to separate mics in a mix with Studio One

Hey guys,

I am having a bit of trouble running the mics through separate AUX channels in Studio One. I can make the channels but I cannot seem to link the mics to each individual track and it is becoming quite frustrating as I really want to mix the mics and as I find I could probably get a better mix by separating the mics and mixing them individually.

If any one has any tips and tricks please let me know.

Thank you.
