sMART

In sMART, when you are using the Administer Destinations function (adding a location), it is very time consuming when you have a large utility footprint and you are required to enter the County, Latitude and Longitude for each new location as this isn't something that we keep on each of our locations.  Is there a need for Zip and County?  Could you not use City/State?  Is there a way for the application to pull the latitude/longitude based on the address that we enter?
