I've got a question about ships. AO3 puts friendships, and even the parent-child relationship when the story focuses on it in the "relationships" category, albeit separated with "&".
The ampersand is easily gotten rid of by replacing it with a comma. I can also use regex so that, if the "ship" in question is separated by "&", then it gets deleted via
But just in case the author did not list the characters in question in the field "characters", I'd like to basically put the separated character names into the character name field. Is that possible? And if so, how do I avoid duplication? Can't seem to find out the method for it.
