You can define searches using "Advanced search" under Contacts or Members, then add the full results of the search to your emails using the "+ Contact list" feature. You can also add special internal fields to your database to make this kind of searching easier.
If you just want to add a handful of names on the fly, I agree it would be nice to be able to select more than one at a time.
