Is there any way to copy and paste all aspects of part of a sheet?

I'm currently writing Johann Strauss Sr's Op. 11, "Walzer à la Paganini" but it's separated into 7 sections: waltzes 1 through 6 and a coda.
I want to upload the full 7 section score in its entirety on Musescore but also want to post each section individually as unlisted so I can have a Midi of each part. However, when I copy and paste a section, it doesn't copy barlines, repeats, system text etc. Sometimes it even fiddles with the measure length.
Is there any way of just copy and pasting the whole page exactly as it is into a separate score? It'd help a lot.

Thanks.
