Create a room schedule specifically for a design option.
When you create a new view, such as a room schedule, by default its design option settings are set to Automatic. (See Check the Design Option Settings for a View.) As a result, the room schedule lists all rooms in the main model and all primary options.
To create a room schedule for a design option, create a schedule view and dedicate it to the design option. (See Dedicate Views to a Design Option and Create a Schedule or Quantity.) The room schedule will then list all rooms in the main model and in the specified design options for each option set.
