With the Strip Map Index Features tool, it is possible to generate index features for map series for a line, but not for other geometries.
With the Grid Index Features tool, it is possible to generate index features for map series for points, however they are in a grid and do not have the feature at the center.
With the Feature Envelope to Polygon, it is possible to create index features for map series for (buffered) points with the original features in the center, however without being able to specify the length and width of the index features.
I would like to be able to generate index features for map series for points (polygons would also be nice), with the original features in the center of the index features, but also being able to specify the length and width of the index features.
