Four Bars per Line/System, again :)

[Nils]

Hello Users,

I am currently looking at Realbook layouts and user expectations. 
"Four Bars per Line" in a Leadsheet seems to be a pretty common request.

I know there is the method with a invisible voice that breaks the staffs. But 
this seems like a hack. Using content to force the layout. And it gets tiresome 
if you have longer pieces or time signature changes.

So, is there a different method, probably more layout oriented? I saw there is  
a way to force the systems per page. So is there a bars per lines layout 
command? Or isn't there one?
