Adding what's essentially an Inn Room as an instanced option in an FC House doesn't have any of the constraints they mentioned. You can't move objects in the Company Workshop and I'm completely fine with that. I just want to be able to make glamour plates from my FC House without teleporting to a major city. They don't even have to make an entire instanced area either. The door that leads to the FC chambers could have an option called Storage Closet that brings up the menu for the Glamour Dresser. It wouldn't be an item in the house but a feature from the menu.
