Fretboard diagrams and chord symbols

I have created a palette for my own jazz chord diagrams via the inspector. But I have not been able to find out how to label them. 3 or 4 of them appear in the palette with a chord symbol/name over them eg Am7 and G9 but the more complicated do not eg: A13b9 or Em7b5 or Cdim7.
How can I add the chord name to the diagram?
