Add more bars but keep page layout the same

As seen in the photo, I want to add more bars from the last bar. But since the two bar section is a very important motif that transitions into the chorus, I want to keep the two bar layout, and continue with the three bar from the next page.

Is there a way to add more bars without screwing up the current page formatting?
