Prevent section staves from hiding

Hello Dorico users
I’ve got a piece for solo soprano and SATB chorus. I want to hide the SATB chorus when they’re not singing. So I select Hide Empty Staves in Layout Options. But now I have a point where SAT enter a few bars ahead of B, and Dorico hides the Bass staff on one page and showing only SAT. How can I hide the SATB chorus when they are not singing, yet have the full chorus become visible at once, without a staff disappearing if its part enters later.

If the best solution is to insert an invisible an object in the bars I want to keep visible, then which invisible object should I select?

Thanks for any advice

A space or two of text should handle this… it’s already invisible :slight_smile:

Thanks. Great idea.
