I would like to be able to use the SHAPE field of a feature class in the Definition Query dialog.
Example:
I have two layouts in ArcGIS Pro - one portrait and one landscape. I want to apply a definition query to my data driven pages index that includes only shapes that are taller than they are wide and vice versa (SHAPE.extent.YMax - SHAPE.extent.Ymin > SHAPE.extent.XMax - SHAPE.extent.XMin).
