Adding piano chord diagrams

I am a piano improvisation teacher and specifically use Musescore to transcribe scores for the different students' levels of expertise.

However, because I create about 3000 lead sheets a year, I would very much like to include piano chords diagrams at the beginning of every piece ie the chords required to play the entire piece, just below the Title bar/Composer/Lyricist frame.

Can you please make this for me? I've tried using PNG files of chord diagrams but they never come out clear enough unless you make them huge which will then take away half the page just for that.
