Percussion legend does not copy from score to parts (new version 2022)

[dspreadbury]

Welcome to the forum, @Yung-Ching. There’s no change in Dorico 4 in this regard, I’m afraid, but this would be worth a try:

Percussion legends in full score but not in the parts?

I believe percussion legends are similar to system and frame breaks etc. in that they apply only in tthe layout in which they were created. I’ve not tried this, but you could try filtering for them in the full score, then copy them to the clipboard, switch to the part layout, and paste them there.
