You can also use modules to achieve this.
Each of your Design Option would be in a different module. Naturally only those elements would go into each module file that are different in each Design Option.
You should then create a Layer for each Design Option in the project file and when you place for example Option1, make the Option1 layer the master layer of this Hotlinked Module. When you show/hide the its Master Layer, the whole Hotlinked Module is also shown/hidden.
