Auto-update project after editing template

Hello luca_vezza,

Unfortunately this is not possible out of the box, when creating a project from a template, the project gets created with the tasks from the template at that point in time. Later changes to the project template will not be reflected in previously created projects. It would not be a simple process to keep live inflight projects, where the tasks / structure of the project would / could change, in sync with a project template. 
You could look to build something custom maybe based on your business logic / rules, you could build a Microsoft Project VSTO add-in etc. where the user could click a button on the ribbon to update the project with any new tasks you define. I guess the consistent option would be to place any new tasks at the end of the schedule rather than inserting the tasks.
