Often i accidentally style "body 2" "body 3" instead of remembering to click the dropdown and select "body (all pages)"

It would be great to have an option in the style dropdown to select "apply to (all links) / (all pages) / (all paragraphs) style"

Use case:
I change the body style of one page, i then decide i want all pages to look the same.
Currently i would have to select "body (all pages)" and create the style again from scratch
I would like to have a button that duplicates the style to "Body (all pages)"

Hope i explained that clearly!
