Score Editor Question

Is there any way to add a staff to a part? I did a search in the manual. But I’m not finding anything. So, I guess I’m not using the correct terminology for the search engine.

I have a piano part with the left hand on one track and the right hand on another. I would like to combine the two into a grand staff view. When I blended the two tracks together I got a SINGLE treble staff with both parts printed into ledger line hell. So is there a way that I could extract the two parts and combine them on a blank grand staff?


Which manual? You need the Score Layout and Printing manual?
