It does sound like you would be better off working as one long piece instead of using repeats....

Go to the Edit menu and choose "Unfold (convert to one BIG chorus)". As long as you stay under the 255 measure limit, you can do thing the way you want, when you want...

In the future, when you start a song, choose "1" in the "Choruses" box (set your end to something like 125 - then adjust as needed)
