Finale Staff Setup

I need help setting up a Finale document as a lead sheet with the first 4 bars in piano format and the rest as a single treble clef staff. Basically I want it to look like the attached picture. If someone could enlighten me as to how to do this it would be greatly appreciated.

The easiest way would be to do it all on two staves, leaving empty the ones you won't use. THEN, optimizing them out so they don't appear on the finished product.

It's a little cumbersome though. ;) I can't think of another way though...

Thanks robin. The only problem with that is that the staves stay spaced out. Would I be able to move the staves so they are closer together after I had the bottom one?

It should take out the empty staves entirely, leaving the normal amount of space - or at least allowing you to move them as you see fit. I've run into problems with using groups and staff optimization at the same time. Get rid of any groupings before optimizing, then add them back in if needed.

It's not an exact science... ;)

Alright, I will give it a try. Thanks!
