copy whole bars with repeats etc.

Hello, is there a way to select music and repeats, in other words everything of bars including meters?
When I use the marquee tool only the music gets selected but not the repeats or other special bar lines.

The System Track is very useful for this.

How does it work? I select several tracks with the system track, but then I can’t copy them.

What I want is to select several bars and copy everything into another document including meter changes, repeats etc. How does this work?

If using the system track, here are instructions for selecting material - once selected, copy as normal (Ctrl/Cmd-C). You can also import/export individual flows in case it’s easier for you to import the flow containing the relevant bars into the other document, then delete the bars you don’t need.
