Thanks, but although the above syntax works for verbose fret diagram markup, it
does not appear to work for predefined chord shapes:

flatThree = \markup { \concat { \flat 3 } }

\addChordShape  #'CmShape
                                #ukulele-tuning
                                #'(
                                (place-fret 4 1 5)
                                (place-fret 3 4 ,flatThree)
                                (place-fret 2 4 5)
                                (place-fret 1 4 "R")
                                )

\storePredefinedDiagram #default-fret-table \chordmode { des'':m }
                        #ukulele-tuning
                        #(chord-shape 'CmShape ukulele-tuning)

mychords = \chordmode{
        des'':m
}

<<
        \context FretBoards {
                \set stringTunings = #ukulele-tuning
                \override FretBoard
                        #'(fret-diagram-details finger-code) = #'in-dot
                \mychords

The error messages I get are:

programming error: markup head has no markup signature
continuing, cross fingers
