It would be nice to be able to copy-paste a legend within an MXD (and also between MXDs) without it defaulting to the basic legend structure (i.e., all layers in the map, default spacing, etc.). I want the newly-copied legend to have the exact same structure and items (layers) that the original legend has.
When copying between MXD's the newly-copied legend should only include the layers with the same names as in the original legend (if any). --Some of my maps are very similar (possibly with different objects and images shown on the layout) and changing the legend in one map means I have to make the same changes across all maps.
It would be nice if copying legends copied every detail of the structure.
