Keeping all Toggl entries in Google Calendar (not just the last 2 weeks)

That would be great! In the meantime, is there a guide on how we can manually do this until the feature is shipped? (Eg exporting all past Toggl entries for the past month to gcal, and that this won’t duplicate the events on the gcal too many times if we do this every month)
