Selected information can be set as same for a group of students by using Group Assign Student Info. As an example, you can make the Rolling/Retention option as Retain for a bunch of students at once or a generic email ID can be given to all the students. Basically you are enabled to give a generic info for a group of students by this option.
To do so go to Students >> Group Assign Student Info >> Search the students using proper search criteria >> Click on Submit. Now you will get a screen with a few labels that can be changed with a list of students.
Now select the option you want to make change with, select the students you want to apply the changes for and click on Save.
