Using a 'global' variable with multi-bar rests

[Stig Johan Berggren]

Hello!
I'm writing some multi-part scores and am using a 'global' variable to
keep track of things like key and tempo changes. However, this causes
all the multi-bar rests to be expanded when extracting the parts. Is
there a way to avoid this?

Example:

    \version "2.12.3"
    global = { \time 4/4 \skip 1*3 \time 3/4 \skip 2.*2 \bar "|." }
    flute = \relative c'' { R1*3 d2. c }

    \new Staff << \global \flute >>

A workaround or a better way to achieve this would be helpful!
