I just talked to Candice Coots who updated me on this question. The short answer is no. :)

But you should be able to import both calendars to your outlook, so that you could make one flowing personal calendar. If that is what you are after.

Hi Jake, I coach at a small club and our team keeps our events here. A neighboring club has skill clinics on a regular basis that are posted on google calendar (and associated feed). I was hoping to merge those on my weplay team calendar automatically so the team's players and parents could see them as possibilities to register for.

As it is now, I take them and manually enter them into our team weplay calendar.

Thanks for the Outlook thought.
