I have an application with multiple tables to track a number of Projects (master table). Each month, a Project Manager must go in and create a new Update (sub table to Projects) that will be used to populate an Executive Report for each project. Each Update has multiple tables under it (Financials, Timelines, Milestones, etc...). What I'm looking for is when the user Adds and Update to a project, each sub table automatically copies the values from the last update that was submitted for that project. This is because in many cases, most financials or timelines may not change, and I don't want the user to have to start from scratch for each project.
