There's no cheats to use here unfortunately. You cannot have your sim live in Selvadorada too.
However, there is a way to achieve custom sims in this role: merge them into a household "living" in Selvadorada. Simply follow these steps:

1. Travel to Selvadorada to have the game generate Selvadorada households.
2. Take note of sim's names, especially last names. Safe bet is to always look for the vendors in Puerto Llamante Marketplace.
3. Open Manage Households in Manage Worlds and look for households with that last name.
4. Using the Merge Households tool, move in the sims you want to appear as locals in Selvadorada. If you have 8 sims, you may move out that original sim(s) into the household your sim were in.

And that should be enough to have custom local sims appear in Selvadorada.

Template:
Sims generated for this role are child, teen, young adult, adult, or elder sims with Latin name.
