Option to change default template (message-body) on debtors statement

Can we please have an option to change the template of the "default message" on the debtor statement. I understand that the body of the email is editable, but I have to add multiple sentences every time I send them out.

  - alternatively, can the template be saved to the previous edit

Working on multiple school's, this is quite a time consuming process... :(
