Is there a widget out there that would allow me to publish a custom geocoder that would allow my web users to map multiple points from an Excel spreadsheet? For example, if I published a single-field geocoder that matched up with parcel PIN numbers, is there a widget that could grab the PIN from a user-provided spreadsheet and map points through my custom geocoder? I'm thinking that it would be like the Add Data widget, but instead of using the supported fields that are predefined to work with Esri's geocoder, I could have a PIN field.
