When training a classifier via the geoprocessing tools (e.g. 'Train Random Trees Classifier') in Desktop or Pro, there is the option to include additional input data such as vegetation indices or elevation. However, when using the classification wizard in Pro for an object-based classification, it only seems to accept a 3-band segmented raster. It would be intuitive if the same option to provide ancillary raster data were also available in the classification wizard.
