We use a setup where we have subtasks nested within main tasks. eg:
Main task: Bake a cake
Sub tasks: buy ingredients, find recipe, execute recipe
Initially we would like to allocate effort to the main task. eg. "Bake a cake: 6hr". (from feb 1 to feb 4) At a later stage we would like to divide the 6 hrs to the individual subtasks: "buy ingredients Feb 1: 2hr", "find recipe Feb1: 1hr" and "execute recipe Feb4: 3hr".
it would be convenient if when we assign 2 hrs to "buy ingredients", it would subtract that effort from the main task "Bake a cake". To make sub-dividing the effort easier. Can this be configured via automation, calculation fields or other functionality?
