Tacet rehearsal marks -part lay out

Tacet.dorico (1.7 MB)

I want to display the section from Rehearsal Marks 2 through 5 as a multi-bar rest with a long bar, and add the text “Tacet.” How can I do this?

I would like to change the section marked in the middle to look like the example above.

I would like to make the green-highlighted section look like the example above.

Should I add more to the flow?

This is a really bad idea. Suppose the conductor wants to start at rehearsal 4?
