I would like to know whether it is possible to make a volume in the post-processing step?

My simulation includes a huge box that contains a building. I had meshed this geometry with ICEM, and then it has been simulated using fluent. In this step, I need to make a small box in the internal part of the building. I want to make this box to find the average velocity in a particular space, while the volume integral only calculates the average velocity of the whole unit,

It would be much appreciated if you could please assist me.
