How to selectively show hidden staffs which are hidden through "Hide empty staves" under Layout options

Dear Doricorians,

How can I selectively show hidden staffs which are hidden through “Hide empty staves” under Layout options?

Is it possible at present?

My workaround is to create a dummy playing technique in each empty bar and then hide it…you can do this quickly with copy and paste. If you want the system to show then it will…If you don’t want the system to show, simply delete the dummy playing techniques and it will disappear…This is with Hiding set to ‘Always.’ Use Galley View to manage as all bars are always shown in this view.

Thank you for the method! It works well!
