Guitar Chords

For my own compositions, I place guitar chords (i.e., A, E) above the staff using the text field. This works OK, but many of the chords I play are not the standard configurations on the fretboard. I would like to create a "visual glossary" of these chord configurations, a picture for each chord showing the six strings and the little dots where the fingers go! Maybe I could create chord 'picture files' and splice these into the open area below the last staff. Any ideas on how to do this?

Thanks. Jim
