Is there a way for a music function to operate on the note that precedes it?

Rather than try to work around the plumbing of LilyPond, might I suggest the following:

\version "2.20.0"

noteTemplate =
  (reference-note) (ly:music?)
    (pitch) (ly:pitch?)
    (let ((note (ly:music-deep-copy reference-note)))
      (ly:music-set-property! note 'pitch pitch)

middle = \noteTemplate 2^"*"
final = \noteTemplate 2.--

\fixed c' { \cadenzaOn a4 g \middle b g8[ f] g4_( \final c') \bar "|" }
\fixed c' { \cadenzaOn g4 f8[ d] e4 \middle e g4 a \final g \bar "|" }

This approach allows you to create a template of sorts for individual notes. Above is an example usage to aid with pointing, supporting the middle of a phrase and the final tone.
