You choose some new names for the arrowed pitches, and add them to the 
list, along with the original quartertones.  Something like



arrowedPitchNames = #`(
       (ceses . ,(ly:make-pitch -1 0 DOUBLE-FLAT))
       (ceseh . ,(ly:make-pitch -1 0 (* FLAT 3/2)))
       (cesel . ,(ly:make-pitch -1 0 FLAT-LOWER))
       (ces   . ,(ly:make-pitch -1 0 FLAT))
       (cesir . ,(ly:make-pitch -1 0 FLAT-RAISE))
       (cesih . ,(ly:make-pitch -1 0 (/ FLAT 2)))
       (ceh . ,(ly:make-pitch -1 0 (/ FLAT 2)))
       (cel   . ,(ly:make-pitch -1 0 NATURAL-LOWER))
       (c     . ,(ly:make-pitch -1 0 NATURAL))
       (cir   . ,(ly:make-pitch -1 0 NATURAL-RAISE))
       (cih . ,(ly:make-pitch -1 0 (/ SHARP 2)))
       (ciseh . ,(ly:make-pitch -1 0 (/ SHARP 2)))
       (cisel . ,(ly:make-pitch -1 0 SHARP-LOWER))
       (cis   . ,(ly:make-pitch -1 0 SHARP))
       (cisir . ,(ly:make-pitch -1 0 SHARP-RAISE))
       (cisih . ,(ly:make-pitch -1 0 (* SHARP 3/2)))
       (cisis . ,(ly:make-pitch -1 0 DOUBLE-SHARP))
...
