I’ve created a Module for auto filling Titles using Custom Fields or whatever you might want. This is handy for Channels like People, that you want to store a First and Last name, and want the title to be a joint of those fields, but don’t want to have your users enter that info twice. It will be a commercial add-on, but I am looking for some beta testers. If this is something you might be interested in, either PM me or DM me on twitter (@marcato15) your email address.
