After a case has been started, is it possible to give an estimate of the time remaining, rather than the total time needed?
E.g. I estimate a task as one day, then after half a day I realize there's more work that I hadn't considered, so I think it'll take 2 additional days of work (for a total of 2.5 days).
It would be nice if I could enter an estimate for the remaining work, rather than having to update the total estimate (which I forget to do, then get confused when the 'renaming time' column looks wrong).
