Playback track ids

I have imported a mix cd, audacity has separated the tracks, I have put them back together and the mix runs fine. But I want to add the track ids back in so when I play it back on an iPod or similar, you can skip to the next track in the mix. I will be exporting the finished project as a MP3

Can anyone help please?

Many thanks

Is this what you’re trying to do?
