Our site (and many other sites) use custom marks to give partial credit for missing assignments so that students don't fall so far behind that they can't catch up. However, because we don't give 0s for missing work, the student portal shows that students have no missing assignments when, in fact, they have many. This confuses parents and students. Is it possible to provide the option to link the missing assignments feature to custom marks if a school doesn't give 0s for missing work.
