Selecting surfaces across multiple faces on Sketchup/OS

asked Jun 18

updated Jun 19

Hi, I have this high rise building that I built on sketchup with the openstudio plugin. I want to add glazing to the building. Since all surfaces are not glazed, I have to manually select the surfaces to which I can apply a Window to Wall Ratio. Each level of the building has been drawn as one space. Is there a way I can select surfaces from multiple places and then apply the Window to Wall ratio at one go? Thanks
