Did the suggestion from the post help you with the use case? If so, be sure you return to the post and use the Accept as Solution button on that post to give the poster credit for the assistance and let other Community Members know the solution worked.
If you are still trying to sort things out, leave an update with what additional help you require. The only other thing I have is a link to the Design Blog area of Communiity, you can search there to see if you can find something that might fit too. There are usually multiple ways to do things, but the post should work from what I can see, not sure if there is something more efficient potentially or not. My post will also kick things back up, and someone else may have another look and potentially offer up a different idea too.
