Export custom noteheads, lines, clefs, etc. in another project

Hi, everybody,
Does it’s possible to export customized objects, like noteheads, lines, clefs, in another project?
I have to merge together two projects with an unconventional notation and, therefore, with a lot of customized elements. So I’m searching a way to avoid creating again all these symbols.

Thanks in advance

I suggest you look at the Library>Library Manager. It’s easy to see what differs between projects and move customisations around (without upsetting the Dorico defaults)

You can also, in the project where these custom items exist, click the star icon for them in the corresponding editor dialog – this “saves them as default” to your user library, making them available in multiple projects.

Oh it works!
Thankyou very much!
