Modal window when clicking on a student via Student Attendance should be editable . If you go to Academics > Attendance > Student Attendance, you're able to click on any student's name from this screen. A new modal will pop up with additional details for that specific student. You should be able to edit the attendance information/notes that displays in this modal instead of having to visit the student's Academic Profile or find all instances for this particular student to edit from the Student Attendance screen
