Sometimes, you start a Group Message and realize later that you need to add a new person to the conversation, or remove someone from the conversation.

Currently, there is no way to add/remove someone from a conversation. A new Group conversation has to be started, but all of the previous discussion details are lost, or have to be copied and pasted, one at a time, into a new Group conversation.

Please add the ability to add/remove people to/from an existing Group Message.
