Store locator updates through UI instead of CSV file

We are a wholesaler that supply many different companies with our products.  On our website we have a store locator for each of these companies with a map as well.  We use longitude and latitude for the map part.  Up until now we have been using a .csv file to store and update the website information. 

I would like to know if there is a way to add a custom tab to the customer records that will include all of the store locator information.  Then NetSuite would take this information and automatically update our website.  The reason we would like to do this is to allow anyone in our company to easily update that information. Most of the employees are unfamiliar with .csv files and NetSuite in general.  This would give us an easy to use UI for this process and save a lot of time.
