Searching for Buckling Modes in Specific Body of the Model

Folks,

I am running an eigenvalue buckling analysis (ANTYPE,BUCKLE).  Is there a way to tell the software to only search for buckling modes in certain bodies of the model?  In other words, suppose I have a vacuum tank comprised of a shell and two heads.  If I only want to find the buckling modes in one of the heads, is there a way to tell the software to do that?
