Hi. I need to import an Excel spreadsheet of addresses with the usual columns (street, city, state, etc). I have another column called "Visited" with yes/no. I want to be able to import the entire list of addresses, but only show a push pin for those places visited. I also want to be able to toggle the visibility of the push pins based on a "yes" in the "Visited" column. How can I do this? Thanks!
