Multi column document list with bulk download tick box

Is there a way to display a multi-column list of documents from a category and its sub categories, showing the Category+subcategory name, document name and details and a tick box to add the document to the mass download list? We have divided several training modules into sub-topics and I want users to be able to select a module, see all the documents in all the sub-topics and download the whole lot from that view rather than having to go into every sub-topic separately.

The closest I can find is to use the eDocman Documents module, which gives a list of documents, but no multi-select download options on the page. Also, despite having selected 'Show Category' in the module's config, this is not appearing on the page - see images.

Thanks
