Ability to have a mix of team member and team estimates in capacity planning

When we are less certain about a future project, we add capacity at the team level. As we know more, or as team members roll into the project, we add individual capacities. At the moment you can't have team (header level) and member (child level) estimates at the same time as the calculations (sums) no longer work. ** We currently create a member as a pseudo team to get around this limitation at the moment.
