Selective unsubscribe option

Allow individual emails and phone numbers to opt out of text and/or emails. Due to the fact that contacts can have multiple emails and phone numbers associated with them. Not all the numbers are the actual contact some, can be wrong numbers old numbers or associates. This would allow the ability to weed out bad numbers without completely unsubscribing the entire contact and other phone numbers and emails associated with the contact that have not requested to opt out This would be most helpful when utilizing cold skip traced data that could have multiple faulty numbers and emails that may not be the actual contact.
