Changing that it doesnt overlap

Dorico makes this not so practical layout. How can I chang this automatically so?

Smaller staff (space) size or one fewer systems per page.

thx and how can a put them on the top as it is in the advertisment of dorico 5?

I guess its in layout. the space of the systems I could make smaller that helpt.

ok found it Songbook Layout erstellen

In the English version of Dorico at least, we call the array of diagrams before the music starts a “used chord diagrams grid”. There’s a Layout Option to show those.
