Can not clone template graphs on host

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.
