Percussion map file format

When creating or editing a percussion map and exporting it, what file format does Dorico use.

For importing a percussion map, can Dorico use the .drm format that Cubase uses for drum maps?

Percussion maps are exported in Dorico’s own library file format; no other program can open that format. It’s really only designed for going back and forth between different Dorico projects.

Thank you for the clarification.
