Two flows in the same page

Hello,

I’m confused about how to have two flows in the same page.

I have two short guitar duos that take two system each. By default, there’s one flow on each page, and so there’s the title/composer frame, the flow frame, and then more than half the page of empty space.

How can I have the two flows (including title and composer frame for each flow) on the same page?

Thank you,
Stéphane.

Thank you very much.
