You can override #description on the instance side to either build  
your descriptions on the fly or to modify the ones returned by the  
class. For example:

    B>>description
       ^ super description collect: [ :each |
          (each isKindOf: MAToManyDescription)
             ifTrue: [ each copy classes: self dynamicClasses ]
             ifFalse: [ each ] ]

You find many other possible solutions in the mailing-list archive and  
some additional information in the FAQ:
