Google calendar now lets you choose which observances you want to see/hide. But when viewing on Dakboard all observances are showing, even those that I've marked to hide in my Google calendar. Anyone know how to fix this?

Account Holiday calendars now provide the ability to select/deselect certain holidays. The linked discussion shows screenshots from the client on the feature.

See if this information can be identified through the API and if we can hide/show appropriately.
