Need a Way to Remove All Releases

I need to regularly compare only Chrome for consecutive releases. To do this I need to first remove nearly everything that's shown by default. If I could just "remove all" and add back the one's I need it would be much faster.

I do this because I'm primarily responsible for [documenting new Chrome APIs on MDN](https://developer.mozilla.org/en-US/dashboards/revisions?user=jpmedley). I run the resulting csv file through a script that pings MDN and reports which items are missing. I plan to share this script tech writer colleagues at other browser vendors.
