Allow adding contacts to blacklist
I have a contact called "Telemarketers/Spam" that I assign spam callers to, so they're all in one place. In the past, this made it easy to block them, since I could just block that contact. For whatever reason, Google has apparently deemed it wise to remove that ability, so I can't do it anymore, and not only can't I do it in YACB, but I have to choose between the possibility, albeit unlikely, of having a contact blocked, or setting it to never block contacts, in which case all those spammers will get through. I'd like to be able to add the contact, and all the numbers under it, to the blacklist.
