Fretboard detail on page below bars

As a beginner I document my guitar lessons and would like to add fretboard diagram details below the Staff.
I've included an example.

It would be automagicaly great if a function can split the page and display all used chords on the bottom half of the page. Preferably in a independent size, ready for adding finger nr's,
colors or whatever anyone needs to get the job done learning chords.
