Metronome marks above piano staff of vocal score?

[Steven Smith]

Is there a a way to have the metronome mark created by "\tempo 4=80" 
appear next to the piano staff as well as above the top staff of a 
SATB/Piano score? My research indicates that this placement is fairly 
common in choral pieces. Also, some submission typesetting guidelines of 
various contest suggest that metronome marks appear above certain staff 
groups in orchestral scores (top of score,string section, percussion, etc).
