Don,I would say no..but there is more then one way to skin a cat..
You could record a style that you play, and save it as an SMF..Add lyrics to the file..
Add 4 markers..

Now as you play the file,filter the parts that get in the way of your realtime play..
Use the realtime phrases ..6 of them.variation of guitar strums etc..As you play left hand chords, the phrases will follow in sync....Chords will show on the display.
You can save this file as part of your User program..
This would give you all the flexibility of a style, with total control for your performance..
