VERIFIED SOLUTION i
If there is a key map defined in a template (or an Active Content) then its content can be imported from external resource generated by Key Map Generator.
Existing Key Map content can be updated using Update button
After updating the existing key map the new resource contains new images and EngageOne will merge them with the existing ones by adding new key names to the list. The corresponding images will also be added in the appropriate folder and this functionality works as desired.
However, there is also a wild card key map feature and according to the Administration Guide, it is an effective way to provide all of the required images from a given location and to pass in the name of the image to be pulled dynamically through the data using EngageOne Interactive or a custom application.
The functionality works fine when used to import images for a new Key Map but in attempt to update a Key Map when having already a Key Map imported and updating it with a wildcard Key Map archive then new name will be added to the existing list as it is shown above (name Science on the image)
The feature currently works as designed and was not classified as a bug.
