Question about recording mixes in traktor 2

I have traktor 2 and an audio 10 interface. I’m using 2 turntables and an external mixer, I want to record my mixes how can I do this in traktor 2

route the output from the mixer back into one of the inputs on the A10 and select those inputs as the recording source in TP2 prefs.
