In reality, you have lots of options, including playing the LIVE! Keep in mind, however, the vast majority of the audiences have absolutely no idea that we're playing, or for that matter, singing. They walk up to you in the middle of a song, ask if you have THIS or THAT IN THERE, and that while you're singing your heart out. The canned intros are pretty damned good and in many instances, much better than most performers could play on their own. If you want an intro that is exactly like the intro of a particular song, you can sit down, create the intro, save it in the style file, then rename the style file with the song title. Same goes for the endings. This, obviously, takes time and effort on your part. The manufacturers provided us with the options, but it's up to us to utilize them.
Cheers,
Gary
