Good idea.
Until F&S has this, the Interactive Schedule lets you do it (depending on your requirements) ... generate an appropriately filtered and sorted schedule preview, select the desired elements, and click the Select button. No substitute for your wish in efficiency since the IS Preview window is modal and has to be closed to do anything to the selected elements, change floors, etc...and doesn't select in 3D. Your wish is the right solution IMHO.
