TextSpanners distintos y superpuestos que comparten música

[Kelvin Angeles]

Hola a todos, espero que se encuentren bien. He estado buscando alguna forma para crear 2 TextSpanners que compartan música y estén superpuestos (Uno encima del otro sin que el primero genere conflicto con el segundo).

Aquí les comparto lo que intenté hacer. Les estaré muy agradecido si tuviesen alguna solución. :')

%  TextSpanner 1  %

startOne = #(define-music-function (music) (ly:music?) #{
  \override TextSpanner.bound-details.left.text = \markup { \halign #-0.8 \small "TextSpanner 1" }
 
  #music
  \startTextSpan
#})

stopOne = #(define-music-function (music) (ly:music?) #{
  \revert TextSpanner.bound-details.left.text
 
  #music
  \stopTextSpan
#})

%%%%%%%%%%%%%%%%%%%
%  TextSpanner 2  %
%%%%%%%%%%%%%%%%%%%

startTwo = #(define-music-function (music) (ly:music?) #{
  \override TextSpanner.bound-details.left.text = \markup { \halign #-0.8 \small "TextSpanner 2" }
 
  #music
  \startTextSpan
#})

stopTwo = #(define-music-function (music) (ly:music?) #{
  \revert TextSpanner.bound-details.left.text
 
  #music
  \stopTextSpan
