You can add a "Test Extra Points" column with "0" points assigned and then give them the points they earned. Personally, I downloaded the gradebook, added a new column for "Test Extra Points", then uploaded it back (so that all the student names were there and in the correct format).
NOTE #1: All uploads (for some reason) go into ASSIGNMENTS. That's OK. Once they're all uploaded (Tests/Finals/EC Points), simply move them to the category that they are supposed to go in.
NOTE #2: You have to add the "0" points into a category that exists - it can't be its own category as you can't divide by 0.
