Using a standard Google Analytics configuration, which characteristics cannot be used to create a custom segment?

A segment is a subset of your Analytics data. For example, of your entire set of users, one segment might be users from a particular country or city. Another segment might be users who purchase a particular line of products or who visit a specific part of your site. A segment is made up of one or more non-destructive filters (filters that do not alter the underlying data). Those filters isolate subsets of users, sessions, and hits: Subsets of users: for example, users who have previously purchased; users who added items to their shopping carts, but didn’t complete a purchase; Subsets of sessions: for example, all sessions originating from Campaign A; all sessions during which a purchase occurred. Subsets of hits: for example, all hits in which revenue was greater than $10.
