Here's a video tutorial (6 meg) that will show you how to use the Linked XForm modifier to control the position of windows and window openings in a wall in 3ds Max easily and efficiently.
Again, while this particular example is windows in the window openings, it's really the concept that you want to learn from the tutorial so that you can apply it to situations that make sense in your production. I've only applied it to two windows here, but there is no limit to the number of objects and Dummy objects it could be used for extremely complex scenarios.
Good luck and have fun.
