I would like to be able to create a kind of template for something like a project comprising a set of tasks and events. From the due date of the target event, I would register a set of tasks and event concurring to the achievement of the target event; these tasks and event would not have a due date but a calculated date (e.g. 10 days before target event, 5 weeks before target event, 3 months before target event). Using this template and the due date of the target event, Pocket Informant would calculate the exact dates of the different tasks and events and populate the calendar
