Customising student email notification when assignment is graded

Hi all!

I'm using Moodle 2.7.2 which someone else has built and I am a site admin for.

I want to configure the email that students when an assignment is graded.

I know there is a default email notification that goes out once marks and grades are saved (and that you can choose whether to send this email). But I want to customise the text and any URLs in that email.

There may be another way to do this, but I am wanting to encourage students to go and look at the feedback on assignments.

Cheers!
