What do you need another communication tab for? Please can you give a little more information?

Again, please could you give a bit more detail about what you are after so we can best help you.
Inside the current communications tab, you are able to scan or import communications. Send letters, emails, and text messages. As well as monitor a patient's recall information.
How is having another one of these tabs going to help? I am sure I am just misunderstanding something, so please give more detail on what you are after and I will do my best to give you the answer you are looking for.
