Currently, Ortho Mapping in ArcGIS Pro supports the orthorectification of both a collection of satellite scenes and a single satellite scene.

However, for aerial imagery and scanned aerial imagery, only a collection of multiple imagery scenes is supported. I cannot orthorectify a single aerial imagery scene in ArcGIS Pro.
It would be great to have this capability implemented because using a single ortho as another option for aerial imagery as well.
