I have no experience in this but: Is it easy to change unwanted chords using the Notation window and then Freeze the track?

May be a pain but may solve this problem temporarily.
I encounter it also but would like to learn the easiest way to solve it.

I agree all styles should be offered as Simple and Embellished just as PG is now giving us more "Dry" instruments we can color our own way using Amplitube etc.
