I'd like to be able to create a new release and have the schedule be templatized so that the detailed dates correspond to the overall release dates. I thought I would have this capability by copying a release, but the detailed dates do not correspond to a scheduled template.
I apologize if this already exists.
This can be achieved via Settings -> Product -> Release phases and milestones. You can create a template and each time you create a new release, you can choose to use your template. This will allow you to use the specified phases and milestones.
