Tags and how to import them via csv

Hey, i’ve got two question about the tags.

Is there a way to import the passwords and give them the tags right there? Giving every single item one or more tags would be aweful, we’ve got about 1300 passwords.
Is there a kind of bulk action, i mean where can give the items tags just by droping them on the left side where youve got all your tags.
Currently were just using the demoversion in mozilla firefox.
Thanks for the help guys
