I have a task with an estimate of 2 weeks that has a sub-task with an estimate of 2 days. Is it possible to move the sub-task only into a sprint rather than the whole task? If I move the whole task (which we can't complete in a single sprint) it throws our stats out because the burndown always has an extra 2 weeks of incomplete work on it!
Do I need to turn the parent task into a story so that it won't be counted in the burndown or can I just place the sub-task into a sprint somehow?
