Two different floor- or wallfinishes in a room

Hi,

I have a room with two different floor- and wallfinishes. How can i get the area of the finishes combined with the roomnumber?

I guess i have to model the finishes as a wall or floor, since my roomschedule has only one entry for floorfinish for a given room.

Having done that, how to get the roomnumber and finish?
