Set Default Templates

create template for client message, info on invoices, footers, documents. I do not like the pre filled in client message, I have to tell the chat agent to change it every time. I also want to include a personalized message when I send out an invoice like I can with a proposal. I also want to include my signature with my name, title, contact info email and number on all my messages. At this time I have to manually add it in.
