[SDF-49366] User Groups & Announcements - Email the User Group?

In SDP it's possible to make announcements visible to a user group.
However there is also an option to email individuals when creating an announcement.

Is it possible to email the User Group or would a distribution list need to be set up in MS Exchange and then add it as a User in SDP?

Thank you
David
