Add second column called duration thats recursive

this is similiar to the sum of value trees below… but a difference use case

I as looking the radial map view of goal scape and was impressed with the visual way you can set goals and subgoals.

If we take away the visual aspect, It would be STUPENDOUS to have an outline that has a Main Heading of My day with a duration attribute of 24 hours… and then sub items with durations that add up to 24.
if all is not used then it gets an unassigned item.
