2 paths to consider. I’ve used both. One way, you do the fix and the other way, the Sound Mixer does the fix.
Yes to your actual question if the tracks 1 & 2 you mention belong to the 23 tracks in question and they are all in the one source.
If this is so, with your completed Sequence, you can duplicate track 1 21 times. Then, (for example) take the track that should be Source track 3, select all the clips on it, right-click one of those clips to bring up the menu and select the option ‘Change Source Track’ and select A3. Do this with the remaining tracks, changing them to A4, A5 etc.
Another way I’ve achieved this with my Sound Mixer who uses a program other than ProTools, is to send an EDL of the track with Track 1 audio on it plus the original 23 source file and he conforms that EDL to give him all 23 tracks for every edit. Not sure if ProTools is capable of doing that, but, if you talk to your Mixer, they might know how to make it work.
Howpe all that helps.
