I create a new event with another event nested inside.
I set this event as a Default (good for templating).
I create a new event based on that Default.
I see it still references that original nested event and the parameter. Which is desirable in some cases, but in others, I want to separate them, and I don’t see a way to choose.
As Alcibiade rightly points out, this is possible if you’re using nested events instead of referenced events.
This will work as long as they’re local parameters. If they are, the new parameters will reference the same preset parameters as the old, but since you want them to be identical to the originals, that’s desirable.
