Is there a way to get the list of contacts in a message or message chain or put them in a group

Is there a way to get the list of contacts in a message or message chain in Messages app on iOS.

At one time when I looked for a way to do this there was no available way without jailbreaking. Has anything changed? Is there a way to do this now?
