How to add more icon into component set

Hi, can anyone please help to tell me how can I add more icon into a component set?
With other component set like just text or button or something that I can edit easily, I can duplicate one in a component set and edit it. But when I have a new icon it’s just something packed and cannot be edit , so I don’t know how to add that new icon into a component set. Thank you .
