(Sorry, for double posting. I put the first one in the wrong place, I think)

In a score with only one instrument, I cannot figure out how to make a multimeasure rest bar that is only one "physical" measure long.

I tried to:
Mark, say, 5 measures. 
Right click in the marked area
Select Multimeasure rests
Select Create.

That gives me a rest bar with "5" written above it. But the bar is still 5 measures long, so that no space is saved.

Please, give me a rest :-)
