How to create blank staves?

Very helpful! One question: I’ve done all the steps Daniel described. When I do them, I end up with 3 systems that go all the way across the page and one that is very short. If I add a system, then I get what you see in the screenshot. Is there a way to get four systems on page 1 without having to resort to an extra system on an otherwise blank second page? Did I miss something? Thank you!
