Currently the only way I found to enter an estimate in a sub-task is to log some work (mandatory field in time tracker) and then set the remaining manually in the same screen. But actually I need to do that in a planning stage when I don't log work (hours) yet.
And also, when I log work in the sub-tasks, I would like to have them deducted from the remaining estimate of both the sub-task and the user story.
The main purpose of this is to have an accurate burndown chart in hours.
Is it possible to configure the tool to get this scenario? If not, could you please recomend a workaround for it?
Thanks!
