In The Sims 4, it is possible to modify any sim in your neighborhood once you start the game.
You can add sims to your currently family, you can change motives, happiness.. even teleport them around the neighborhood.
There are a couple commands you have to enter before you can do this however.
How to Edit Sims in The Sims 4
First you need to access the Sims 4 cheat console.
To pull up the console, hit Ctrl+Shift+C (or Cmd+Shift+C on a Mac) on your keyboard.
Once the cheat console is up, type in testing cheats true and hit enter.
Once Testing Cheats is turned on, type cas.fulleditmode and hit enter.
Once that is done, you’ll be able to shift click on sims, which will pop up additional options in the menu.
