Discarding local changes of calendar event in Akonadi

I’m using Google calendar through KOrganizer and I changed one recurring meeting that I’m not owner of. KOrganizer warned me that change will be saved only locally and I was fine with it. After doing my changes, then the whole recurrence was messed up somehow. Luckily it was indeed messed up only locally - looking at the event from Google Calendar, it looks fine still.

So I’d like now to just discard my local changes to the event. Does anybody know if and how this could be done? Perhaps through Akonadi Console somehow?
