In Organization Settings under "Map and scene" you can select Default basemap for maps. Now any new map will have the new basemap. Having to manually update 100's of Web Maps basemap is painful. If we could have a button maybe called "Batch Select Maps to Update" this would fast track the process of getting every map updated with the current imagery.
For all maps that have had the previous defaulted basemap, if they will update to the new default would help.
Here is a photo where I think this new feature could go for a button saying "Batch Select Maps to Update".
