I had to turn off the welcome messages entirely because for many clients I need to make small changes that are relevant to the package they buy. I end up sending welcome messages via email instead. It would be great to do everything through trainerize and have the option to edit the welcome message template prior to sending it out (without altering the entire message template) so if I need to add or remove an details for one particular new client it will be easy to do so without changing the entire auto message and then changing it back after sending the invite.
