Hi Rodney and thanks for getting in touch!
Excellent question. You can definitely use our Filter Bar add-on to allow your visitors to filter event search results to very narrowed results. This will add a set of filters to the calendar that visitors can use to narrow events down to a number of different variables, such as time, venue, organizer, day of the week, category and tags. It can even support custom fields if you also have Events Calendar PRO installed.
And, yes, you can add as many locations (we call them “Venues”) as you would like to the filters.
Does this help answer your questions? Please let me know. 🙂
Cheers!
Geoff
