That is not part of the Store Locator Plus functionality. There are other plugins that can help you with that.
For future reference, whereas we do not monitor this WP SLP forum often.
Please use the Store Locator Plus forums to post general plug-in questions. Be sure to follow the Forum Posting Guidelines and provide the information (including your plugin environment) requested so that we can assist you. If you need customization you can contacts us using the Customization form on our home page
Using the forums to ask questions helps eliminate redundancy. Posting in the forum allows us to be more efficient with our time and thorough with our answers. Forums will get you a quicker response. We give forums priority over direct email questions as it often helps several users with a single response.
To post in the forums, login with the same email and password you used to make your purchases at StoreLocatorPlus.com. If you have not created a login yet you can do so for free by “purchasing” the free Forum Registration.
