Is there a way to access the list of names used by the game?

Honestly, I would love to have a straight answer to this as well. The name lists for this game in languages other than English tend to be absolutely abysmal, and I'd like to define the lists myself instead of desperately trying to find a mod that fits my needs. (which is very unlikely to exist btw)

I'd like to add more names to the randomizer! I get so many townies with the same five surnames and it's driving me mad.

The Sims 3's namelist was way better in my language, way more variety, so I'd love to import that into TS4 somehow.
