We need a "Series Ends With Cliffhanger" Checkbox

How can we get IMDb to add one piece of data to a show -- does the series end with an unresolved cliffhanger? I don't want to waste my time watching a series (no matter how good it might be) that ends with a cliffhanger that's never resolved because the series was cancelled. A couple lose endings, I don't mind -- but an actual "OMG, what's going to happen?!?!" and then the series is cancelled?

Please give us something (without scrolling through all the comments looking for spoiler warnings) that's easy to see right up front. I always check IMDb before starting to watch something -- help me not give my attention to the shows that don't respect the fans.
