Currently, that's the only way to do it.
The closed-loop verification will (hopefully) soon be mandatory, and when we do this, there will probably be some way to add a list and do some sort of confirmation then - my guess is that we'll allow customers to edit the text of this message to at least some extent (like adding a welcome message).
Not currently (as far as I know). This might be a good feature to add. I'll post this link to Josh so that he can maybe comment further.
