In order to be able to create meaningful reports from the Structure tab of a Part structure we need to be able to select what subtypes that shall be visable in the part structure. Today you can only select if you want to see Documents or not.
In the Show/Hide related information, you should be able to, not only select type, but also sub-type. So for CAD Documents and Documents you should be able to e.g. only show Described By documents or e.g. Software parts.
