A mod or way to prevent sims from appearing in other neighborhoods?

They are tourists. I'm fine with my sims visiting other worlds but in my game, as far as I see, when you visit, let's say a bar, I mostly see the sims who live in that area. So locals already have some type of priority in game in terms of spawning in public lots. But it's not 100% of course, I see other worlds' sims as well. It's just ok for me.
