How do I temporarily switch to two staffs?

So, I'm writing a piece for my school orchestra to play, and some of the divisis are too complex to put on the same staff, so I need to put them on another staff, but not a staff that will be there throughout the whole score, because said divisis are only in a few measures. I added a picture of what I mean written on paper as an example. Is there any way I can do this in musescore? Thank you!
