Hey there and thanks for posting. I understand getting this up is really important to you. This is, however, something that would have to be designed by the software developer of the device you're using. Some phones do have this feature, and it could just be hidden. What kind of device are you using? We may be able to look into some different settings to see if ti's an option.
After the recent update on my Galaxy S8 Plus my contact text notifications were set to default and the option to change them has disappeared
