Changing character information (Real Name, etc)

Question: Is there a way to edit a character’s name and information without having to create a whole new entry for said character?

For example: In entering info for the recent Kickstarter-funded “Shieldmaster: Blast to the Past” book, I had to create an entry for Simon & Kirby’s Bullseye character. When I did so, I mistakenly made the entry “Bulls Eye (Simon & Kirby)” rather than “Bullseye (Simon & Kirby)”.

Is there a way I can fix that? And also go back in and add real names where they’re not present?
