I am exporting the data related to the client from our database to EXEL file then from the exel file to map point. Map point Maps all client under the one pushpin set. Now i want to add a client directly in to map point map. then i want to update my database. But i am not able to do this becouse new client does not come under the previouse puspin set. A new pushpin set is created. Please help

I can see two solutions. First, without programming, you could export the two pushpin sets to Excel, combine them there, and import them again as a single pushpin set. Second, you could write some code that takes a manually added pushpin and merge it into the first pushpin set. Neither of them is elegant, but both would achieve the desired end result.
