Best way to go about it is using tags. Basically, tags allow you to track virtually anything you want, locally, and to filter on it as well.
Just create a tag called "insert" or something like that and very each DVD that has one, tick it. You can then filter on that tag to show only DVD's that have an insert or the opposite, that don't have one.
Tags work with a check box so all you need to do once the tag is created, is check it per DVD that has one.
Hope that helps |
