Howdy there magenta2389195 and thanks for coming to our site!
From what I've seen, this isn't something a phone's native app will do. If this is possible, it'll most likely be a 3rd party app that you'll need to do the trick.
As for the discussion, are you asking about how the is going to appear when someone replies back? Please let us know. Thanks!

magenta2389195 there is a setting in the messaging app for my Galaxy S8+
Settings -> More Settings -> Multimedia Messages -> Group conversation (checkbox)
Disabled this sends the message one at a time to all the recipients...
Enabled sends a group MMS message.
Is that what you were looking for?
