Smart Content and Not-So-Smart Content

hadeletlakhalom

I have a decent amount of content that came directly from daz, and a decent amount that has come from 3rd party stores.  All of the stuff from daz shows up in smart content, and a good chunk of the 3rd party stuff does.  But I am finding that there is a lot still that doesn't.  I understand I can edit metadata for each of the products that do not show up in smart content, so that they will show.  However, trying to go through every single item in the content pane and see if it is in the smart content pane is... just exhausting to think about.  Is there a way to get the program to just give me a list of everything that *isn't* in the smart content pane?  Like a list-everything-without-metadata function or something?
