reset sim info?

Many of my sims in my gallery are saved from their games rather than straight from cas, i only want to save their designs not their other info you know? since they are saved from actuall games they retain things like their job info and public image and i dont know what else. i cant help but worry that because of this some of them might carry hidden errors from broken games or somthing. i might be over thinking it and i dont know if im making perfect sense here but does anyone know if theres a way to erase any saved data on them? (and i dont mean by erasing tray files or somthing) i know that mc command center can erase relationship but it would be helpful to completely reset a sim to its ...er for lack of a better term, factory settings. so it keeps the design and such but any saved data can be erased?

Again dont know if i'm making perfect sense here, and i'm not sure if general chat is the best place for this but i didnt feel like modding request was the appropriate place either.
