I'd like roll to all happen on one screen and have a yes and no option for all students

Regardless of whether a student is a drop in, trial, registered for the season, or using a punch card they should all be on one roll page to make it simple for instructors. Then admin can assign payment method after or it can be selected automatically based on settings in the clients account. I'd also like to be able to select present or absent since sometimes I can't tell if a student was missing or just didn't get marked that week.
