Is There a Way to Unlink Audio Tracks?

We're just testing it out and seeing how it feels right now. Say you have your voiceover track be your main track and it's in ripple mode and everything's linked to that then switch it to a video track for instance. All those clips unlink and relink to new clips on the video track is most likely the way it will work. Along with that you're going to be able to hide tracks mute different tracks and you track headers for locking can you go into what the locking and all that is? You know say you're doing a show that needs to be 59 minutes and 10 seconds you could make your music track or you're I attract that length and then lock it down
