A few Questions.

I'm a beginner at Musescore 3 and I couldn't find answers to my questions in the handbook.
Can someone help me?

1. Can I make a "cut" through one element to put another through it?
2. How can I change an Instrument's name?
3. In an orchestra score, how can I separate the instruments into pages for each instrument?

4. How do I get the conductor's page?

   Thank You
