Only had Biab for a day now so I'm still trying to figure some of it out, it's confusing to me how everything is considered a chorus when I am thinking like intro-verses-chorus-bridge-solo etc

I know somehow it can be done but I cant figure out how to name them different then have them play back in the right order?
say I have 4 parts is a song and want them to play 1 - 2- 3- 1 - 3- 4 etc.
