Changing the number of instruments mid-score

Hey,
I use Musescore for arranging jazz tunes a lot. In the head of the tune, for example, I want to be able to notate for all the instruments.
However, once the solo section is reached, I'd love to be able to have just one stave on one page showing the chord chart, rather than having to have 6 instruments' staves for just chord symbols.

Really appreciate any help!
