Do CAS stories seem useless?

Can't speak for everyone, but this seems like a tool many of us have been asking for for a while in terms of world building. Some players like to create their own townies, and then set them free for their played sims to interact with. As it is, that's been REALLY difficult, cause you have to go in and play each sim to "set them up" as it were. And since you can't even get most NPC jobs in played households, it's virtually impossible--ie: only possible with cheats, and really freakin' convoluted ones at that--to, say, create your own librarians and such. I don't know if NPC jobs will be included as a possibility for jobs you can assign in CAS, but if it is, that feature alone would make things way easier for those of us who don't just pick one household and play it through, but like to create the whole world our sim exists in.
