Is there anything I can do to get this credits accepted?

Im trying to add "Detective" title to the characters names in Homicide Life on the Street as has been done with Law & Order franchise https://www.imdb.com/title/tt0098844/ https://www.imdb.com/title/tt0203259/ & https://www.imdb.com/title/tt0098844

I only do it for the main characters who are listed in the opening credits. I do this because seeing main characters have "Detective" in the titles of imdb enforces that its a police procedrual and most of the guest characters refer to them as Detective [insert last name].  Just wondering if theres anyhing i can do to get the credits accpted thanks.
