Unclear if this is Bug or Improvement, calling it bug as buttons are present but unusable which is unexpected based on other features.
When you link a template to a host, you can go to that host's items, open a template item, and clone it. This is great. However, when you go to the graphs on the host, you can NOT clone a template graph. This is unfortunate as it would be a great time saver. If I could clone a graph, rename it, and change it's data points (akin to the edits I can make for items when cloning), I would not need to rebuild the graph from scratch on the host. I also can't copy the graph from the template because the copy operation has no edit functions in it wherein I might rename when copying. It would be a convenience if cloning of graphs worked like cloning of items.
