Hi Gabriel,
Thanks for taking the time to reach out! If you’re looking to combine event data from multiple Google Calendars into a single changeable calendar view, you’ll likely want to start with our Event Aggregator tool, which allows for one-time or recurring event imports from a variety of sources (including Google Calendar). When you’re importing events from each of your individual calendars, you can assign a separate category or tag to the events from each calendar, which will then allow you to view all events in a single view (with the default view), view each set of events as its own separate calendar (using a category or tag view, as seen here on our WP Shindig demo site), or view events from a combination of one or more calendars (using Filter Bar to filter by the appropriate categories or tags).
I hope that helps to get you started here! Thanks again, and let me know if you should have any other questions here! 🙂
