Nope, has to be an item, Triggers can't be Items. You'd need Badspot to code Triggers in to v1.03 as a something to save. Btw, triggers are invisible, what's the point of saying "invisible item" when triggers are invisible. Everyone stop suggesting datablocks other then items to be saved onto a brick like an item you set, it's not possible unless Badspot puts it into the DSO'd code.
