how can I change the notification email templates?

Hello,

I would like your help to change the text that appear on the automatic emails that Sugar send with the assignments notification.

I have a customer who changed the names of the modules but when he receive an assignments emails the name that appear is the default name and not the costume name. Also, this client needs to put additional information on the templates.

I was looking in PDF templates but I can not find these emails templates. I would appreciate your comment about where and how I can make these changes.
