Set flows to new page manually

I have set my layout, so that new flows are allowed on the same page.
Is ti possible, to have set selected flows on a new page though?

Best Regards

Yep, insert a frame break at the start of those flows.

The TL;DR version is:

Click the barline or first note where you want a new page to start, and press shift-F in engrave mode to insert a frame break.

Thank you very much
