iCloud has shifted all my local calendars to the cloud and has in the process removed all the groupings I had set up. How can I group iCloud calendars? Using File>New Calendar Group in the Lion application just creates a local group on my MacBook but not on the cloud. I can't see any way to do it for the iCloud calendars, either from the MacBook or via icloud.com. (I don't have an iOS device, so I don't know how or whether one might help.) Thanks.
