Welcome to BB forums
Right now I don't think that is feature could be in future OS update.
But for now I seen friend of mine JSanders suggested this app SMSbyNow group texts, you can do quick search in AppWorld
Has per emails you can add more contacts if you like you should see on your right hand corner + tap on that will bring you to your contacts or you can type out the email address.
