Can I Revert from extracted to original audio

I sent some audio files from Premiere Pro to Audition have them as 'audio extracted' in my timeline. Is there an easy way to revert to the original sound file without re-inserting the entire clip?

It's not an undo or a revert. It's audio I've sent to audition and it's been returned. If you apply a visual effect, you can delete or toggle the effect off from the effects tab. I was wondering if there is something like that for audio that's been edited in audition.
