Currently, your clients can only select one room at a time enabling them to add their details specific to just that room (e.g. budget, colors, what’s staying vs going, dimensions, room photos, etc.).
The Room/Spaces is the first section your client will see when opening the questionnaire. There are 12 rooms that your clients can choose from and an option (Other) they can use if they have something to add that is not on the list. See the Updating Project Details Questionnaire article for a quick glance at the Rooms/Spaces section.
It is also worth noting that you can manage which rooms/spaces will be displayed in the Questionnaire. You can select the rooms/spaces under the Settings menu and access its PROJECT QUESTIONNAIRE tab. See Updating the questions in the Questionnaire article for more information.
