There are multiple ways to accomplish this utilizing both BIAB and RB.
Simple method in BIAB is to generate chords for the song as a whole as you normally would. Freeze all tracks except the guitar. Edit the chord chart with your desired embellished guitar chords and generate, which will only generate the guitar track but with the chord embellishments you made.

In RB you can generate multiple tracks or sections of tracks or multi-riffs and copy/paste sections to compose a unique track from all of the generated tracks. This can be done the same as the above BIAB guitar track in RB by generating only the guitar track or track section with chord embellishments too.
