Notorious Notes Niggling

It may be something I've asked before, but isn't there some way of importing notes into TX_CUST_NOTES or TX_CUST_NOTES_EXT? Or is it necessary for people to do this manually? I've got a list of about 258 new notes (for a new note type that was created) that I need to get in there and I'm not sure how to do this by the [Tessitura] book.

Thanks, Tessiturians.
