multiple markups

[Jean-marc LEGRAND]

Hi list !

I'm using lily2.4 on XP.

I have to put a rcomma AND a fingering on the same note. I'de like to have the 
fingering just on top
of the note, but the rcomma just on the right, so at a different level.
I make :

\once \override TextScript #'extra-offset = #'(2.2 . -2) c8.^2 ^\tr. The 2 is 
well on the top of the
note, but tr doesn't "want" to move where I want.

question : how can I have "separate override" ?

One issue is to put the ^\tr on the next note and adapt the override, but I'd 
prefer a more honest
way !

Regards
