[Koha] patrons in a school setting

hello under patrons what would be a natual choice to add class data. I'm in a school pre-k thru 6 with 4 section each like 6-2, 6-3, 5-1 5-2, 5-3 etc. Each year the classes are mixed. some students from 5-2 will find themselves in 6-1 with stusdents from 5-1...5-4. They all have the same patron user capability. It would be nice to list overdue reports bases on section number. thanks in advance re-v __________________________________ Do you Yahoo!?
