Multiple Physical Locations

I thought I read that I could do this but not seeing how to accomplish.
I have some business that have 3 to 5 locations. How do I accomplish setting this up or allowing the business owner that creates the listing to set this up? How would it look in the listing after entered, for example if there are 3 pizza shops how will that info be shown in the listing? Right now a map is already showing on the page. How would the 2 other locations be displayed? Is there a way to have 3 listings and show different data for 3 listings? Here is what I mean, we have 3 locations, one of the 3 locations is a grand opening and we want to show a special just for that location. The way that the directory listing works is all fields are on that listing page and we don’t see a way to show the multiple locations. But if it will just be another area to drop in another two addresses with a link to get the directions on a map then we would not know of a way to show different info/fields based on which of the 3 locations that are on the listing. This ability to show different data is secondary to the may question here which is how do I enter/show more than one physical location on a listing?
