When you put in the cheat for the llama, you also unlock a hidden cheat. Hold down LT and click on a sim and you can either force age them or change their traits, if it is a sim not in your family you can force age them or add them to active family.
You can also hold down LT and click on the mailbox, like in Sims 2 PC, and do many things such as setting your sim into a certain career or forcing certain sims to come to your place.
