Enable "Reply All" in text messages

[jaggrey]

I have the threaded texting disabled. I made a folder with preaddressed templates for sending out group messages. To do this I would hit "reply all" on the text message, and it would automatically give me a blank message with the addresses already populated.

For some reason "Reply All" is greyed out! I tried that Reply All fix for emails but that didn't do anything.

Any ideas on how I can enable "Reply All" in text messages? Right now it only give me the option to Forward.
