Changing percussion parts to five line stave

Hi,
Im looking to change my single line orchestral percussion parts to one five line stave. From what I’ve found online it seems like you have to go to layout options, players, percussion, but I don’t have percussion as an option in layout options. Has there been an update that has moved this function?

Any help would be greatly appreciated.
Thanks!

That option only appears (under Layout Options >Players) if one has a multi-line unpitched Percussion instrument (like Bongos or a Kit as opposed to a Brake Drum) assigned to the score in Setup.

Thankyou. Does this mean that you can change a multi-line stave to a single line stave but not the other way around?

No, you can add your existing single-line percussion instrument to a kit, and then you can use the option described by @Derrek.

To do that, right-click on the player in the Players panel in Setup mode and choose Combine Instruments Into Kit from the context menu.

Ahhhh I see! Thankyou!
