For Elementary Schools, where do I click to mark a student tardy?

Elementary Schools NEVER mark a student tardy.  The office (or in some schools, the teacher) marks the student with a code of 19, Late To School, in the In column.  That populates the Out column with the time of the beginning of your school day, a 52 in the Code column, an E in the Ex column, and Temporarily Excused in the Out Reason.
