AutoCAD Architecture :: Change Selection Of Scheduled Objects In External Drawing

I have three drawing constructs.I have door tags and room tags. I have schedules. All work just fine. However, I need to combine all three Finish and all three Door schedules into one multi-level schedule for each, doors and finishes. In views, I schedule the external references by selecting the YES option in the properties dialog box. The problem is that the drawing contains doors and spaces that I do not want to be part of the schedule. How do I deselect the objects that I want to be in the schedule?

The other problem is I can only select one drawing. It makes no sense to have separate schedules for each floor on a small project where there are only 10-20 rooms. As a work around I can create the schedules in constructs, import all the constructs into a view, clip all the constructs and the stitch the tables together. This is cumbersome, does not update seamlessly and results in unnecessary file sizes.
