Right now, if I want to add columns, change filters, rename the report, or change who it is shared with, I have to cancel and reschedule it. The system appears to allow you to add names to the Share list after the report is scheduled, but the recipient does not receive the report unless you cancel and reschedule it. With staff turnover and events being added to the system, having to cancel and reschedule all of these reports is time prohibitive.
