[gatein-dev] Deploying an archive to a specific server implementation

I want to be able to deploy a different war on the Tomcat and JBoss implementations of GateIn. This is the integration.war used to tie into the wci. Currently we are using the patch process to patch in the integration.war. This war is now going to have a jar added and it makes sense to create an actual archive than to continue using the patch process. Is it possible to deploy a war depending on which server is going to be used? I have looked through the packaging module and have tried adding a few things to the server patch section but I can't seem to get it to work. Or can this only be done by editing and updating exopackage/exobuild?
