Bar Fermata at end of system?

[N. Andrew Walsh]

I have a block of music in which the \bar "||" has a fermata over it, and which I want to be the end of a system. My Voice for organizing barring and breaking thus has this line:

Voice {

   \time 2/4

   \tempo \markup {\sans \medium \fontsize #4 "Andantè"}

   s2*72 \mark \markup { \musicglyph #"scripts.ufermata" } \bar "||" \break 

   \time 4/4

  }

However, that puts the fermata at the *beginning* of the next system. How do I get the fermata at the end of the system (ie, floating over the double bar)?

Cheers,

A
