Importing email address list into address book

[eldoctore]

Hi folks, sure there is a way to do this, can't quite get it to work/find out how to.
Object of exercise is to pick up say 20 email addresses from an email header and import them into a dedicated group within address book. Cutting and pasting leaves the firs name with a "card" containing the rest. Sure I must be overlooking the obvious.

So there really is no way to pick up a list of addressees from an email and export them to Address book, importing them there as a discrete group?
Can't believe it, sure there must be a way!
