Restricting played sims from showing up on lots outside their world?

I have an idea. You know those icon labels of the neighborhood names? It would be great to have a pop-up menu with settings for each neighborhood within the world.

It could look something like the menus from other sim games that let you control certain buildings. So you can have options like:

Allow walk-bys
Townie Generation
Allow visitors from other neighborhoods
Allow celebrities
Allow strays
Maybe even decide if each neighborhood can spawn a festival

If you have seasons installed:
Neighborhood weather - so you can set some neighborhoods as more rainy or cloudy

If Eco Lifestyle is installed:
Neighborhood footprint - decide the footprint for each hood
