Adding fields to struct within variable editor

If I open a struct in the variable editor, I can edit the values of its existing fields there, but I can't see how to add new fields. Is it possible to do so?

From within the variable editor window:

Right click -> New

Then modify the field's value to whatever you like.

No problem!

I don't see a "New" only

Duplicate

Insert

Delete

Rename

Edit Value

I don't see any effect with Duplicate or Insert, and don't want to use Delete.
