When we duplicate a project that has many milestones, all of them with specific start and due dates, even if we change the start and due date of the overall project. Supposing that the original project has start date 01/01/2020 and we duplicate this project, changing the year to 2021: it would be nice if all of the start and due dates of milestones follows this change from ´2020´ to ´2021´ automatically. Right now, if we duplicate a project and change its start and due date, all the milestones have the same start and due date of the original project, incluind the year: we have to do all the changes manually, something that could be quite cumbersome if we are dealing with a large project with plenty of milestones.
