Dependent fields

Any plans in the roadmap to include a dependent-like type field? I mean let’s take a task with a start date depending on the ending date of several precedent tasks. Whenever I change the end date of one or more precedent tasks, it should trigger the change of the start date of the dependent task to the oldest present ending. It should be done a s a build-in feature, I suggest using a special field type for that,
