Allow customization for email notifications by group

Description - We need to edit the subject lines for our system email notifications but would like to do it only for one group, not system-wide. Can this functionality be added to customize by group?

Why is this feature important to you - Different groups use the system in different ways, one size does not fit all.

How would you like the feature to work - Ability to set email notifications and custom subject lines by group for best user experience.

Current Behaviour - The Program Name is now more important for our marketing group's work. This may or may not be the case for our learning group. I would like to customize the email subject for marketing to include the program but cannot do so without making sure it won't impact our learning group.
