Percussion stave between grand staff of harp

Is this possible? This is for a percussive extended technique notation on a harp grand staff:

One way of achieving that is to have two harp players and a percussion player, and hide one staff of each of the harp players, as in the attached project. You will need to change the staff labels.

Thanks. That’s not ideal because the extended technique is only for a few parts in the whole piece. I think the ideal solution would be the ability to add a staff above (like we can now) but be able to choose what type of staff it is. For now, I’ll just notate the percussion on the treble staff.

An easier way: You can put the notes in a 1-line percussion instrument, with x-noteheads, and add a cue in the bottom staff of the harp. This will show between the staves, just without a staff line or clef (which don’t add any information anyway).

By default the Harp-part layout shows the cue and not the percussion instrument. If you need to use Score layout for some reason, you can make it do the same.
