I am building a model where I need the output to match the extent of another raster. The other raster is set as a variable in the model. In ArcGIS 10.1 I was able to set the extent of the model output to "Same as variable X". In ArcGIS Pro this is not an option. I can select a particular file as the extent but the extent needs to be variable. I am wondering if this functionality is just not available in ArcGIS Pro.
