This function of assigning/reassigning an object to a layer set should at least be able to be done in Home Designer PRO. I bought a library set for Utility Vehicles and these items were put on the interior fixtures layer set so now when I want to turn off my tractor in my garage it turns off all other fixtures in the layer set. That's dumb! and its not professional for a PRO version of the software. There should be able to add multiple user layer sets that we can put items into similar to the user library. Please add this feature to fix its failings.
