[Finale] Easy way to do multi-movements?

[DeliusFan]

Is there any way to combine files into one if you have been working on movements separately, or is there a kind of "section break" feature to enable you to create a whole new set of staves without messing up the work you have already done?  I see lots of scores where if the movements don't end at the bottom of the page (especially in a piece with a multitude of short movements) they just take up with the next movement on the same page (provided there's sufficient room, of course!) and I am betting dollars to donuts they were made with Finale.

Thanks in advance,
