When you update the channel on a recurring calendar event in Sunsama, that change is now automatically applied to all other instances of that recurring event.
This change isn't retroactive, so if you have previously assigned some recurring events to channels, you will need to re-assign them once per recurring event.
But going forward, you should only ever need to assign the channel once per event.
Less manual labor woo!
PS If you try this out and don't see the change applied to future events, you might need to refresh your page once.
