Filter the feedback widget based on URL

I am interested in specifying a page identifier as one of the feedback widget properties. In my dream world, the widget options would include an origin property and I would stuff my page title into it. It would look something like this:
feedback_widget_options.origin = encodeURIComponent(document.title);

I'm not exactly sure if this question submitted by smnbss is what I'm looking for, but it sounds like it might be in the ballpark... Just checking to see if this is still in beta or is it commonly available yet?
