X-map import without new symbols and techniques (?/Request)

when importing an expression map into a project, it does not appear that any userdefined playback symbols or techniques are imported.
Many of them were not defined as a global standard and are only used in special situations.
Or did I miss something?
Would be a nice option if I didn’t have to recreate them by hand.
This is not possible even with extensive maps.

Greetings to the team and thanks for everything.

Unfortunately the techniques in the Cubase expression map are simply defined as strings, and there’s no underlying meaning to them, so it’s difficult for Dorico to try to figure out what they should map to.

Thanks Daniel,
So now I’m trying to use some global symbols like “xy1-n” and storing the information I need in the X-Map. In the score I can add a text suffix if necessary.
