Enrolling a Group - issue with new functionality

I am using the new Enroll Group functionality and question if I am the only person that finds it very unhelpful that when you pull a large group of students to work with, for example grade 9 students, the list sorts in alpha order by the student's preferred FIRST name, not by last name. There is no ability to sort students by last name for the ability to quickly check off the needed students in bulk to group enroll. The old enroll group was sorted by last name, then first. All BB student lists should allow for sorting by last name alpha. I called Customer Service with no resolution.
