fill last measure with rests

[Jim Tisdall]

Is there a directive that will automatically fill
the last measure with rests?

For instance,
if the music ends on a quarter note on the first
beat of a 4/4 measure, the directive would
fill that measure with 3 beats of rests so that
the measure is filled to the bar line?

(I'm generating scores algorithmically and this
would be a pleasant shortcut ...)

Peace,
Jim
