nOOb question: adding effects to atmospheric gizmos

Hello all.

Im working on a project which requires large number of boxGizmos of different sizes,
achiving it via max script was not a tough job BUT since, ive created over 50 gizmos, it gets hard for me to add "volume fog" to them one by one. Is there any way around to do this job through max script?

Any help would be appreciated.
