I have a number of summary tasks that I want to allocate a fixed amount of time to while still allowing them to be auto scheduled based on other dependencies.
Currently there are two modes:
1) If I set the summary task to auto scheduled, it will expand and contract to it's sub tasks.
2) If I set it to manually scheduled it will stay to a set duration but it won't move with it's dependencies as they expand and contract.
Question
Both of these modes make sense to me but I would like a hybrid where I can define a fixed duration but then allow it to move with it's dependencies. Is this possible?
More Background
One use case is I know how long a phase is but I want to be able to enter individual tasks without worrying about them perfectly aligning to the phase duration. Similar to scrum.
Currently I add a general task at the top of the list that sets it to the duration but this seems like a hack.
