Would it be possible to show instrument parts only at the beginning of a musical work?

Would it be possible to show instrument parts only at the beginning of a musical work? Having the individual parts clearly marked at the start is fine. And I understand that it is necessary to differentiate parts in scores. But it is not always necessary or desirable to have the parts repeatedly marked at the beginning of every line of music for projects that are not scores.

Perhaps providing an option for " score or other musical work" when someone prepares a new template.

What about templates that require piano and a solo, i.e. voice or instrument? Or duets of the same instrument, i.e. duo pianos, two trumpets, etc.?

Is it currently possible to alter the text of instrument names/parts on the actual page like one can alter the title or tempo?

Another thought might be to simply allow users to add as many nameless staves as they wish to a project template. Then they can either insert the cleffs they desire or type the name of the instruments directly on the page. There could also be an option for users to simply not show instrument names at all.

I tried finding ways to do any of the above suggestions and read the manual several times. If I missed something and these suggestions are already possible then please point me in the right direction. Thank you. :)

P.S. I just want to say a huge THANK YOU to Musescore and all its developers. I could never afford the fancy composition programs and Musescore is a God send! And its FREE no less! I am so happy!
