Ability to exclude individual students from particular subject sessions. For example, we have some external students attend a VET subject once per week. The subject involves one practical session per week (which our external VET students are required to attend), and also a number of online sessions at other times during the week (which our external VET students are NOT required to attend). Currently, the only way of excluding these students from these sessions is to add a School Activity (Exempt). This is messy and takes time to set up. We need to be able to toggle these students off the sessions that they are not required to attend, so that their attendance data is not affected and so that we may continue to include these students on Progress Checks and Semester Reports.
