Is it possible to have different page sizes in a single document?

The problem that I’m trying to solve is preparing music examples for a book. The most convenient method, for me, is to have a new flow (and new page) for each music example. However, I’d like the music examples (and therefore the pages in my Dorico document containing the music examples) to have different widths. For example, an 8 bar example should get full width on the typeset book page, while a 4 bar example would need only half or even a third of that width.

Any suggestions are very welcome!

You can have different layouts, each with a different width, and then select which flows you want in each layout.

Thank you very much!
