Click on Select Action and scroll down to Modify Columns . Click Go . If you want to hide or not release any of the default columns, you can change their attributes accordingly. Marking Hidden as yes, allows the column to be hidden from the faculty-designer. This is useful if there are too many columns or some of the default columns aren't needed.
Marking Released as no, allows the column to be hidden from the students.
Then click Update . Click on Add a Column and then Go . Name the column whatever you like. Click on Manage Images . Click on Select Action and scroll down to Add and click Go .
