Hide bracket on condensed staff? nevermind, found it. SOLVED

I’d like a sub-bracket for when both staves are showing (for example, two flute staves), but if they are condensed at some point onto a single staff I’d like there to be NO sub-bracket.

I KNOW I’ve done this, but for the life of me, I can’t remember what wording to search for to find the answer.
How the heck do I do this again???


never mind, of COURSE I had to find it 3 seconds after posting this.
It’s under Brackets and Braces / Layout options.
