i don't know of a way of doing that while actually playing in Build Mode either....the ONLY thing i can think of is actually placing a UNIQUE Catalog Thumbnail for each Mod is S4S, for each .package file. Depending on how many Mods you have...could be a long project. ;°P
Make a note of your house set up (Or catalog set up in categories you know you have CC in) with screenshots or something. Close the game and pull out your mods folder. Boot the game back up and see what's missing
