Just looking at the source code...could i extend the JPAWorkItemManager to achive this?  For example:

in JPAWorkItemManager 

public void internalExecuteWorkItem(WorkItem workItem) {
        Environment env = this.kruntime.getEnvironment();

        WorkItemInfo workItemInfo = new WorkItemInfo(workItem, env);

        PersistenceContext context = ((PersistenceContextManager) env.get( EnvironmentName.PERSISTENCE_CONTEXT_MANAGER )).getCommandScopedPersistenceContext();
        context.persist( workItemInfo );

        ((WorkItemImpl) workItem).setId(workItemInfo.getId());
        workItemInfo.update();

if (this.workItems == null) {
this.workItems = new HashMap<Long, WorkItemInfo>();
        }
workItems.put(workItem.getId(), workItemInfo);

        WorkItemHandler handler = (WorkItemHandler) this.workItemHandlers.get(workItem.getName());
if (handler != null) {

if (handler instanceof StatefulKnowledgeSessionAware) {
                                  //invoke a different execute and inject the session into this?
                            handler.executeWorkItemWithSession(workItem, this, kruntime);
                  } else {
                            handler.executeWorkItem(workItem, this);
                  }
        } else {
            throwWorkItemNotFoundException( workItem );
        }
    }


Would this work?  If so would i register a custom JPAWorkItemManager other than creating my own version of this...
