Make more CQB/CQC?

Would it be possible to create more indoor close combat/battle (CQB/CQC)?

Im thinking to program the AI to stay “indoor” in buildings on some maps. Not all maps ofcourse.

Just did Bionic Fortress (think it was called). Many big buildings/lots of room.
Instead of enemy running around outside the buildings, make it intense room to room clearing of the buildings …
(Make the AI stay on tiles “A” and not go out onto tiles “B” perhaps?)

UFO Aftermath I remember like having some of that aspect.
