Addind new field into notification email templates

Hello,

I want change Lead assignment email template and add some other fields.My analysis show thjat I can change texts and remove any field, but can not addany new field which was not prviously in the template section.
I have used both include/language/en_us.notify_template.html and custom/include/language/en_us.notify_template.html . The result was the same with both.
Do you have any suggestion?
