The only way I can think of is to grab the Userview's JSON definition file in the Userview. In the Userview Builder, look for "Advanced:JSON Definition". Then click on it to copy the definition. Then, paste it in your editor to edit it. Please read this article before trying anything: Duplicate Userview, which links to an article on duplicating form.
Disclaimer: Please read up on JSON here: http://json.org/. Edit the JSON definition at your own risk. I suggest for you to back up the app first
