Push instance override to new component variant

When I’m working with components, sometimes I don’t plan for all states ahead of time, and find myself overriding elements within an instance. I’d love to be able to push an override to the main component, creating a new variant of that component, instead of having to return to the main component to go through the process then and there. I think this would be helpful for library/pattern maintenance without disrupting me while I’m in a flow state.
