It is my team's habit to move completed tickets to Done only in the sprint review session. This is to ensure that acceptance criteria etc have been met. Until that time, actually compelted items are parked in a special review columnThis, however, renders burndown charts for the current sprint useless since the Done-condition isn't met until the very last day of the sprint. Is it any way possible to configure the report so that a different status qualifies as the Done criterion, as far as jsut the report is concerned?
