Created region measurement

Hi.

I'm using PowerCivil.

Is it possible somehow to create a region inside any shape (let's say - color green few square objects) so the green color's level is, for example, "Green_area" and later I can giglight (choose) all the green squares by the level and measure it's area with function "D-5 Measurea area"? I mean - so I don; t have to measure each square seperately. For now, when I crate the region, I can measure it's area when it is inside the shape, if I turn off shape's level. I can't measure area not even for single square.

Thanks.
