I have tested it and, as far as I can tell, it isn't possible to get it to an individual within the group itself. This is because you can't set an option to send text message to the person who rejected it; you can only send to specific addresses and groups.
There is no real workaround for this short of setting up individual survey groups for users and then flows off the back of them. This could be very labour intensive to set up.
I hope that I have answered your question. If I have, please like and set as the solution. I hope to answer more of your questions again in the future.
