Is there a way to get a list of CC (and EP, SP, store content) used on a lot? I'm asking because I built a huge festival lot for my neighborhood and people have been asking me to share it, but I really have no idea what non-base-game stuff I used, and making a list by checking each individual object would take months. Still, I'd like to include a list of content needed to make the lot look and work as pictured. there isn't much point in sharing it otherwise.

I remember there was a trick to it in Sims 2, but no luck so far for Sims 3.
