Personalized custom range

Hi all,
How can I create an instrument with a personalized custom range (ambitus) for an ethnic instruments.
Are there in Dorico ‘out of range’ view?

Thank you,

You cannot do this at the moment, I’m afraid, Emil. We do plan to introduce both the ability to create your own instrument types, and to view notes out of range, in due course, but neither feature will be available imminently.

Thank you Daniel!
Thank you for your great job!
