I have a game I run at 1:00 Pm the second Sunday of every month. If there is a way to set that to auto-update after every game, I don't see it. If we could link the game calendar to the Google Calendar, then set that, it'd be perfect. As is I set an event in my google calendar and then copy a link to that into messenger for my gamer peeps to add to theirs. Seems like there might be an easy fix, but I'm not a coder.
