How to reserve more space for fermata mark (to prevent large vertical shifts)

[Reinhold Kainhofer]

In the attached sample file, I have a fermata mark on a baline.
Unfortunately, the notes after the barline are quite high above the
staff, causing the fermata to move up even further:

\relative c''' {
  R1 \mark \markup { \musicglyph #"scripts.ufermata" }
  a4(^"rit." b c) r
}

Does anyone know a way to make the mark reserve more horizontal space
(i.e. shift the following notes to the right) so that the fermata is
placed directly above the staff?

Thanks,
Reinhold
