Hi!
The main reason why I want to have 1-line Ossia staff (or extra stave) above 5-lines staff is to write rhythm for rhythm guitar (first 1-2 bars). Is it possible?
Edit: or, if it is not possible, can I delete somehow this section?

Could you use a cue in the part?

It’s not possible at the moment, I’m afraid, though it is something we would like to enable in future.
Yes, but I have to add one more instrument for this, and there is no line in a cue.
