The functionality of copying a Rule Set is already implemented into the wizard and the cockpit. You find the function in the top right corner of the editor/composer, where two buttons are located.
The third Button from the right lets you export the current Rule Set to a local ATML3 file.
This file can then be downloaded and the Rule Set can be inspected in a text editor.
To import that Rule Set you need to copy that Rule Set into the respective field in the Rule Set import menu.
This way you are able to fill your newly created Rule Set with sentences and properties from an existing Rule Set.
The Rule Set is now duplicated.
After the duplication please contact us about adjusting the access rights for the Rule Set.
