Hi Herb,
Thanks for getting in touch and for your interest in our plugins.
At this time, there is not a baked in feature for multiple calendars. However, there is a way to create something very similar by using categories. So for example the events for Calendar A would all be in the event category A. Then you can call the calendars sorted by category, which essentially shows a calendar with only those events. We have a little FAQ about doing that here. Another option might be to use a multisite, with a sub-site for each region.
Let me know if you have any further questions or can otherwise help out.
Best,
Leah
