The host wall of a door is known to Revit internally but not exposed to the user in any way. It can't be scheduled using out of the box tools. Usign the Revit API a custom application could be written to access this information. it does take programming knowledge to access and use the door's host wall information.
Host Wall and Host Wall Type-based data are among the types of parameter data that Ideate BIMLink supports - see image. Grabbing the area of the wall in which a window is hosted is a similar type of task.
