I may be to have found a solution.
It is written by a help as follows...

-->
If you want a handler in a groupユs script to affect only the objects in 
the group, place the following statement at the beginning of the handler:

   if the owner of the target is not me then pass message

This filters out any objects that are not part of the group.
