Hello, this is my first post on here and my first time using Sibelius so if this is an obvious fix please don’t mind.

I have an assignment to make a piece of music into a practice track. I am wondering if it is possible to add a new part to my piece only in a specific place, so that I don’t have a bunch of rests in this part before its music starts. I tried pressing the “Add or remove” button (with the trumpet on top) and it seems to add or remove parts for the entire piece. Is there a way to add parts that won’t last for the whole piece and don’t start at the beginning? Hopefully this makes sense, I will send a picture that might better illustrate what I am trying to accomplish.

Thank you so much!!
