So this request has two parts.
First:
Create nested passes such that you can create a collection of passes under a single heading. For example, 'action movies' under which you might have a pass set up to record films with 'James Bond' in the description and another with 'mission impossible' in the title. You get the idea. A way of organising the passes section.
Second:
The ability to export / share passes and pass collections. It would allow people to create a collection that might be called '100 best movies of all time' or '10 best kids Christmas movies' or 'all James Bond films'. Once you've loaded the collection, your DVR would look out for those titles as with any other pass.
The above would probably warrant a separate page on your website to highlight / search for particular collections. Perhaps just a section in these forums.
