Make it so switching an email template using Dynamic JO retains the Sender Name and Sender Email Address

Present day, after cloning a dynamic JO program if I want to update the email template, doing so will change the Sender Name, Email and Reply-to fields to whoever swapped the template (usually me). 

This was not the case with the old JO. The sender selections would remain based on the previous selection for that email step. I’d love to see that functionality in the new dynamic JO as well.
