F-7 Bb7 fit in two beats w small font

[boscotom]

It would be nice to be able to fit F-7 Bb7 (or Bb-7 Eb7, etc. II-V change generally?) within two beats using small font. Not sure how easy that would be. (I know we did a workaround over on the Long & Winding Road chart. Workarounds could be just F- Bb7 or or maybe even just Bb7 on fourth beat and let the jazzer assume the minor 7th substitute in cycle of fifths to set up the dom 7 chord.)

quick edit...And I just like the familiarity in so many billions of songs of seeing the entire F-7 Bb7 written out.

Such a great little app. Thank you!
