Clone Default Email Template Model Value

Hi All,

I've managed to create custom email template and hide the existing default email template. I'm looking for a solution to copy the values from existing email template to new email template. so user don't need to enter the email details manually. 

Custom email template is added to send file upload as attachment to emails. Much appreciated if some one could help me at the earliest on this please
