Add instrument staff mid-score

Hi everybody,

can I add a second staff (a system with bracket) but not to the whole score, only at a specific line. For example in my case, the piece contains a guitar and has only single staffs. And in the middle I want to add a second guitar riff or solo or what ever, and I want to connect two staffs, but don't want empty second staff all the piece. Is that possible?

Thanks in advance!
