Esri Maps for SalesForce offers nice functionality to spatially enable records and automatically geocode when addresses are edited. However, geocoders don't always get the location right and sometimes users only have city/state or zipcode level information available. Users need the option to manually adjust geocoded locations by dropping or dragging a pin on the map. This functionality is currently available in Esri Maps for SharePoint. The user can drop a pin to update the location and optionally reverse geocode to update the related address. http://doc.arcgis.com/en/maps-for-sharepoint/office-365/install-and-configure/fix-a-location.htm
Hopefully the code from the Esri Maps for SharePoint app would port over to the Esri Maps for SalesForce app without a substatial development effort.
