Single/Grand Staff

[Pozzi]

I have Finale 25.5.0.259 on a Mac

I started a single-staff Finale file with Wizard setup. As I approach bar 500, I need to move temporarily to a grand staff. Is there a way to do that?

Someone else may have different advice, but I suspect the only way is to have the grand staff throughout, but set up in such a way that you can hide the second stave everywhere except where you need it. This should be easier that I may be making it seem.
