Forum:Bringing things during a move to another world

This may sound a bit silly, but I want to know this. You see, once The Sims 3 Pets comes out, I'd like to move my main family to Appaloosa Plains. However, I've been playing this family for a while, and there are some things I'd like to take with me, the family's gnomes and the graves of dead relatives, for example. The problem is, I'm not sure how to take these to another world without some sort of problem. I'd really rather not loose the graves (or the gnomes, it took me freaking forever to get a baby gnome). So, can I take them by placing them into Family Inventory or one of my Sims' inventories, or is moving them from world to world impossible? Please, I'd really like to know!
