Is there a way to allow user to do a parallel drill down? Current drill down path is not interexchangable. For example, I wanted to show email open_rate and click_through rate trend in drill down. But I can only get open_rate chart first, then go to click-through rate chart based on the selection from open_rate chart or vice versa(sometimes, the selected field may not make sense for the next chart). It will be great a user can decide which drill down chart to see.
Currently different drill paths depending on what is clicked are not available. The only way around this would be trying to do something similar to the Page Analyzer Links I mentioned on your other post.
