In addition to Barry's post.
Using the criteria he noted, you can create a schedule to find and select the empty openings as well.
It can list all occurrences, on all stories, even if on a locked or hidden layer.
Highlight in the list and click the icon (to find in 3D model or 2D plan).
If the layer is locked/hidden, the icon will be dulled out.
Just unlock/show all layers and Bob's your Uncle.
