Commit Dates are killing us

Hi, Commit Dates are really killing us and causing a lot of confusion/frustration with users. e.g. A task is originally scheduled for a certain date and an assigned user clicks 'Work On It', Workfront sets the commit date to the planned date (assuming the user doesn't propose an alternative commit date - and we ask them not to do this). If the task's planned date is later changed, the user's original commit date remains. Our users don't remember to go and update their commit dates on such tasks. This then affects tasks' and projects' projected dates, and more confusingly for the user, it leaves the original commit date on their mini-calendar on the My Work screen. We would love to just be able to switch off the Commit Date functionality completely. As this doesn't appear to be possible, how else can we try to keep the commit dates aligned with the planned dates? There doesn't seem to be a way to centrally edit commit dates (even one-by-one, let alone in bulk). The only way I know of doing this is to log on as the user and change the commit date on each task. This is impractical with thousands of tasks in progress per month. Do other customers have this issue? How do you handle it? We have a team who are in charge of scheduling people at the right time, so we really don't need the users to be setting alternative commit dates. Thanks, David.
