The ability to do a search based on radius (the way you can do real estate searches), using a map and drawing an area, would make creating lists for event invite lists, fundraising meetings, and more, so much easier. As it stands, you have to enter hundreds of zip codes or cities, in order to create a list for a specific region.
You can do it! :) Enjoy and check it out under the address filters in the location section.
This should be marked as solved.
Announcement at bbcon will take care of this...mapping feature coming sometime in 2017.
