Clustered EJB setting at the application level (EAR)

We are using clustering for tests. Our application is an ear-archive which has no information about clustering. If we will built up a cluster, we have to change the ejb-jar.xml to set the clustered-tag on True. This is very intricate. Out support team have to unpack the ear - set the clustered-tag for every bean and so on.

Is it possible to set the clustered-tag all beans in a ear-Archive?
