Relate trophy titles and user titles

I'm trying to gather some basic player statistics from `gamelist/v2/users/$accountId/titles` and `trophy/v1/users/$accountId/trophyTitles`. Unfortunately, `conceptId` appears only in the first request, and the best field to find a game by its name from the second one `trophyTitleName`, which slightly differs from the original game title in lots of cases.

Is there any known api to establish this relationship?
