How to put multiple scores into one sheet?

Hello,

Please think in terms a book-like, you have one short score on a page, there is another score below, independent from the first one and so on. It could be for example exercises for a piano.

I am describing this way, because when I was searching how I should solve I find another problem (not mine) when you would like to add staff for another instrument -- this is NOT my case. In my case, I have single instrument and multiple exercises/chapters/section on single page, those scores are independent of each other.

So how do I add independent score to the music sheet I have score already? If this matter -- for now I am looking for stacking them, one at top, below next, below next, etc. So no multi-column issue here.

I use MuseScore 4.2.0. Thank you in advance.

Kind regards,
