For instance, I'm subscribed to 3 different sports teams calendar. Which is nice for me knowing when games are, but can be cluttering when I'm working. Now I know this is only 3 calendars so it's not a big deal to just uncheck them. But say I wanna add more.
Is there a way I can create a "sports" group or something and add them all in. I believe this feature used to exist, but now I'm on Yosemite and don't see anything like it.
