I use the expanded song format, and add the repeats with the "Repeats/Endings" process. At 255 bars and 4 betas per bar, I more that 8 minutes at 120bpm. That's more than enough for me. But more is always better.

Since the Repeat/Ending is a print function, you are pretty much allowed to do what you want. I often have repeats within repeats inside a "chorus". Tags are not necessary (but available) since you can just drop through the last repeat into the ending or tag. I think the number of repeats (exactly same notation) is unlimited, but you can only have 4 endings, unless of course you can stack them within each other

I have some pretty complex charts built using this method, including multi-line lyrics. And since the underlying song is untouched, you can change instruments, even the melody or style, leaving a simplified printed form for you.
