Is there a cheat or mod to quickly fill all the empty lots I have?

I started a new save and deleted all of the default households, and I have MCCC set up so that only sims from my library will spawn. I don't feel like manually placing every single sim in every lot, so is there a way to automate that? Or at LEAST speed up neighborhood stories? An ingame week could go by and only about two sims will have moved into a lot.
