Combine Multiple Timelines into Single Request


Is there a way to form a single request that returns the results from multiple timelines?

I’d like users of my app to be able to pick between TimelineA, TimelineB, TimelineC. And then have the results dynamically update to display only those chosen. I was hoping there was a means to manipulate the GET statuses/user_timeline parameter so that it would return results from multiple screen_name. But, I’ve not been able to sort it out.

I have seen posts regarding creating a list as a way to combine multiple twitter timelines into one request, and displaying that. I have 10+ timelines I’d like the user to choose from, so creating a separate list for every possible combination isn’t really an option.
