New Dashboard Changes to Legend - Not Helpful!

The recent changes to the Dashboards now allow for multiple versions of legends, which is great. HOWEVER, the 'default' has apparently been updated, which has changed all of the charts (which are many across the brand) that previously had the legend "below", now have the legend "outside" which is more often than not a less attractive way to view. I'm hoping there's a way to reset the default without having to open every single Dashboard, every single page, every single applicable widget in order to put them back the way we had them in the first place??!
