Ability to configure the email notification sent to users after awarding a badge

Feature Request Summary: 

I would like to be able to configure the email notification sent to users after awarding a badge in our community channel. We would like to be able to control the text and subject of the email and have the ability to use variables (like user name and such).

Description/Use Cases: 

We have multiple communities and multiple milestone badges. We grant badges after 5/10/20 posts and the same for comments. We may add more badging. When we award a badge, a generic email is sent to the user. The email text doesn’t generate the thankfulness or excitement we feel when granting these badges. While I understand that the description is in the email and this may be thought of as a way to show this excitement, the description is also shown in the community, so we wanted the description to be short and sweet, not a long-winded celebration.

Business impact of limitation or missing feature:

This enhancement would allow our business to brand our community in a fundamental way, using our terminology and promoting our culture via emails that celebrate community user engagement. We believe that it would increase engagement and client satisfaction.
