Feature Request: Filter to show Parent events only in admin list

Just as the title says – it would be great if we could have an option to filter the list of events on the admin side to show only the “parent” event. My client site has dozens of fitness classes, each recurs for at least 2 months out, PLUS a ton of other events – so the list of all of our events is many pages of pagination. Many of the classes have similar names, so when we search for “strength training” we get a mix of a bunch of classes. If we could just filter to show each of the PARENT class, not display the recurrences, it would make our lives immensely easier!
