Duplication from an existing variant

It would be great if we could create a variant that not only clicks the “add variant” button but also duplicates from an existing one. Because “add variant” duplicates its base form, but I really need a small change from another variant. If this feature exists and I am not aware, sorry in advance. I couldn’t find it. Maybe assigning the current variant’s style to a class and applying it to the new variant is a quick win. idk.
