Secondary Sort Priority

I have a field called GPA which includes numeric data (3.4, 4.2, 1.6) etc. In some cases multiple people have the same gpa. When this happens, I'd like the people to be sorted alphabetically by the name field.

Smith, Adam 4.0
Smith, John 4.0
Smith, Zack 4.0
Smith, Steve 3.9

For example. I saw some multiple sort code in the forum, but also some indication that multiple sort, or sort priority might be coming in a newer version. Is this sort of thing possible/already built in?

Thank you,
Robert
