Loop Button on RECORD?

One question... How the heck do you get the "Loop" button to work when recording? I've searched the Knowledge Base and Forums, can't get a strait answer. I'm tracking drums to a scratch track/clip in the Audition timeline. I'm listening to that while recording 10 tracks made up of my drum microphones. Everything works great, EXCEPT, I have to stop after each take to restart the recording for each take. I lust want it to play back the song over and over again while recording a new Take on each pass. HOW???
