Jim is correct except he doesn't complete the actions to have the 2nd chorus play all 3 chorus's - beginning at Bar 1 chorus 1 and playing through the other two chorus's.

His third option is the correct procedure except saving to an Artist Performance Track is optional. You can leave the track on the Audio Channel without any issue.

Here's the steps to how I would save the second chorus so Chorus 2 would play all three Chorus's.

<<So if you happen to like the performance of the second loop how can you save that so that it plays if like that from the beginning and not just the second time it loops? >>

Render the song to a WAV file and save it in a location you can find.

Import that WAV file onto the Audio Channel.

As example I load a BIAB RealStyle demo file and it's 3 Chorus's each 32 bars then generate the song.

After you've exported the song as a stereo WAV file, import that WAV onto the Audio Channel:

If you open the Audio Editor Window note that bars 1-32 across the top each have a one in brackets (1)
Bars of the second chorus that begins at bar 33 start over at 1 and have a two in brackets (2)
Bars of the third chorus that begins at bar 65 start over at 1 and have a three in brackets (3)
Bar 97 will have end and the following bars will continue with bar 33 and have a three in brackets (3)

This naming convention makes it easy to select the entire second chorus and copy and paste the second chorus at bar 1 of the first and third chorus's respectively. I also select the Snap button so the box is populated with a check mark and this ensures the entire chorus will be highlighted and selected. It also ensures the paste command begins at the very beginning of the chorus bar 1.
Solo the Audio Channel and loop it to repeat as many times as desired and all three chorus's will play the second chorus from the Audio Channel and the other 7 channels will not sound out.
