Apple Mail / Junk Mail / 'select all' Block Contact(s) - can this be done ?

When I check my Apple Mail / Junk Mail I invariably find many Junk messages sent from unidentifiable senders. Is it even possible use a shortcut of some kind to 'select all, then mass block contacts' w/o having to perform this function one address at a time ? Yes, I realize like all pests this alone will not stop these senders from pestering me ... but I would enjoy a small sense of retribution :) Thx.
