Change slur style for all layouts

I’d like certain slurs in my score to be dashed - but it seems that if I do it in the full score, I have to do it again in the parts.

Is it possible to do this once and have all layouts reflect the change?

Of course. Do it in the full score, filter-Select all slurs, and Edit—Propagate Properties.

Ah. Propagate Properties - that’s what I was missing. Thanks!
