Problem with Audition and Premiere

Hello, I'm editing a short movie I made with my friends and we noticed that the audio was really bad and we used audition tu "fix" it. We found after months a person wich studies techinques to clean audios and he needed the audio file of the clips without our modifications. The problem is here, is there something I can do to easly cancel the audio mdifications on the clips, or I have to cut and detach manually every single clip again and sync it on the video?
