I dislike that the game uses my played sims as working NPCs at community lots

Did you use a cheat to edit in CAS? Or how did you do it?

I use the "cas.fulleditmode" cheat before entering CAS through shift-clicking a sim. Not sure if the cheat is needed if you use the "manage households" menu, but I would think so.

You can then edit genetics, and also add family relatio to new sims, but it must be a sim that has not been played. Merging two existing sims to edit their relation will not work.
