Creating inset for fills or rhythm figures

I'm sorry if this has already been addressed, but I don't know the terminology so I couldn't do a proper search. I'd like to create a couple of insets for some guitar music of mine. Guitars 3 and 4 are only playing simple two bar repeating parts, so I don't want to take up two more whole staffs (staves?) to display that. Below is a sample of a random song I found online showing a fill, and I'd like to do something similar. Does Musescore do this?

Thank you.
