How do I populate feature linked annotation class for existing features?

[JohnBerg]

I've created a new feature linked annotation class related to an existing populate feature class.   When I place a new feature the feature linked annotation is created and populated.  How do I handle the already existing data in the feature class so that when I update the attribute in the feature linked annotation the annotation will show ?

Do I need to mass create all the related records?  And if so how?   Can I do it as needed?

Or did I miss some option or different way I should have created the feature linked annotation class which would have handled this?

thanks

That works for items with a row in the annotation table but doesn't help if I already have a bunch of records I'm now creating a link to.

I belive the answer is to use a label expression first and then convert labels to annotation - that covers the existing records.  My mistake was going directly to arccatalog first and creating the linked annotation class but that doesn't populate rows for existing data.
