When editing a normalization, merge or indication rule there is only an option to preview and save. There should also be a "save as" option
What happens now is user edits his rule, is happy with it, then he must copy it to his mouse, create a new rule, and paste it into the new rule. A "save as" would be much more logical. User would do "save" as he does today to change the existing rule, and "save as" to save his changes to a new rule.
