Feature templates is a great improvement in ArcMap’s editing environment. The main disadvantage is that they are available only when creating new features. What about existing features? The power of this editing technique should also be ready to improve and speed up editing of existing features.
Allow to use feature templates to assign default attribute values to existing features by drag and drop (interactively highlight compatible features and preview result while dragging) or simply by double-click on template to apply it to selected features.
