This is, another new nuisance, is hard to explain, but try.

If you have a company lets say, Johns Plumbing and have four names and phone numbers in that card in your contacts. No matter what you do, if send a new text to any of the four, or all of the four people; that text will never get it's own unique new thread in messages, seems Apple always piles it on and blends it with existing thread, right, just because they are under same roof in contracts. HOpe that made sense, baffling to witness.
