Can we "Close All QuickReference Panels"?

I have done a quick search on the forums and web and want to know if we can “Close All QuickReference Panels”? I have many QuickReference Panels open and would like to close them all without finding and selecting them… and don’t really want to close the entire project just to remove the QR Panels…

Any hints or suggestions?

There isn’t a way of doing that at the moment, but it’s already a feature in the upcoming 3.0 update.
