 ### ? - ?
 
+##### Additions :tada:
+
+- Replaced the "Auto Fill" button on `UCesiumFeaturesMetadataComponent` with "Add Properties". This allows metadata properties and feature ID sets to be selectively added to the component, rather than adding them all in bulk.
+
 ##### Fixes :wrench:
 
 - Fixed a bug that prevented `UCesiumPrimitiveFeaturesBlueprintLibrary::GetPrimitiveFeatures` from retrieving the features of instanced meshes.
