If you RightClick on the bar where you want instruments to Rest, then pick "Chord Settings" and take a look a the lower RH side of the little window that opens, you can set the bar to "Rest all Instruments but..."

There are keyboard shortcuts to do this, but using the RightClick at first and having that menu of possibilities is likely the fastest way to learn.

Repeat for each bar where you want instruments to Rest or
"Sit Out".
