Hi Erik!
First of all, I cannot apologize enough for the insane delay in response time here! There are a handful of support threads that for one reason or another seem to have totally fallen through the cracks of our support workflows – I messed up hugely here, and even though I’ve gone through looking for old issues to ensure threads don’t get ignored like this one did, it somehow missed my radar and has been sitting here unaddressed for far, far too long.
As for your question here, it is a fascinating one. By default (so, even without getting the PRO upgrade), you can export individual events to Google Calendar with the “Export to Google Calendar” links on single-event views. However, there is unfortunately not any built-in support for the kind of automatic, mass-exporting functionality you describe in your post here. It may be possible to build something like that with a large amount of custom coding, but at this time it is not within the plugins by default.
Sorry if that’s a disappointment, especially on top of my awful mistake with missing your support thread and taking so long to reply to you – I’m really sorry about that Erik! Let us know what your thoughts are here and if there is anything else we can help you with.
Sincerely,
George
