Temporary percussion staff above a harp grand staff?

Would like to add a one-line percussion staff above a harp grand staff. Is this possible. I know how to add a regular staff, but can’t find a control to turn it into a one-line percussion staff.

TIA

Maybe just give the Harp player also a percussion instrument will do?

(I’ve extended the brace in engrave mode)

Thanks a lot. Can this be hidden and shown as need be throughout the part?

I’m overthinking things. No need to add a percussion instrument to the harpist, just add a percussion player, and add that player to the Harp layout.

With this settings the Harp is always visible, the percussion line only if it contains notes

And at a system break you can force the percussion staff to be visible, even if its empty
