Take a look at this report : Overdues w/ Contact Info https://wiki.koha-community.org/wiki/SQL_Reports_Circulation#Overdues_w.2F_C... b) is it even possible to first generate class-lists and than sort
patreons after class names (like 9a, 9b, 10a, 10b)
You have two choices : a) use ExtendedPatronAttributes to add a custom field that will hold your class / section information https://koha-community.org/manual/20.11/en/html/administration.html#patron-a... b) Use the Sort 1 or Sort 2 fields in your patron record Look up sort1 on the page https://koha-community.org/manual/20.11/en/html/patrons.html Hope this helps.
