Active linking between the same tasks in multiple planners

[JMolfese]

I am working in an educational setting, where content area departments each have their own planner to coordinate their work. Then the district administration has there own planner to coordinate programs and funding streams. There is a lot of overlap between to 2 sets of planners and I often have to manually update tasks between them. It would be really nice to be able to link tasks between planners so that if a task is copied from one planner to another, any changes made in one planner would automatically update in both planners.

Even linking in the same plan would be useful

My organisation also has this requirement. We have project related tasks that are management by a central forum and would like to be able to have a master plan with multiple subplans associated so that the completion status rolls up to the master plan
