Hello Fennel,

if I’m understanding you correctly you wish to see slides between different 
fingerings. One way to go about this would be to assign an arbitrary number to 
the fingering (let’s call id the ID) and then change what is displayed by 
tweaking the text of the fingering. Example:

{
  4-\tweak text "2" _\finger 12345 \glide
  4-\tweak text "3" _\finger 12345
}

here we use the actual fingering of 12345 as "ID", and then actually have it 
display once 2, once 3. We can wrap this in a function:

cfinger =
#(define-music-function (id finger) (index? index-or-markup?)
   #{
     -\tweak text #(if (index? finger) (number->string finger) finger)
     -\finger #id
   #})

{
  4_\cfinger 12345 2 \glide
  4_\cfinger 12345 3
}

Cheers,
Valentin
