You would need to do it in \chordmode but there the "-"-sign has a
different meaning, not to mention that TextScript is not allowed in
ChordNames for this (and probably other) reason(s).

How about:

%% define the new behaviour
chExceptionMusic = {
  <a' c'' d'' e''>1-\markup { m (add 4) }
}

%% add it to other exceptional settings
chExceptions = #(append
                  (sequential-music-to-chord-exceptions chExceptionMusic #t)
                  ignatzekExceptions)

m = {
    <a' c'' d'' e''>1
    \chordmode {
      a:1.3-.4.5
      a:m4.5
    }
}

<<
  \new ChordNames
    %% use the new namings in thos context
    \with { chordNameExceptions = #chExceptions }
    \m
  \new Staff \m
