I am not sure, if this is the best option, but I think it will work.

Create a custom strategy class CustomeFilePersistenceStrategy by extending FilePersistenceStrategy and override getName method as below:

public class CustomeFilePersistenceStrategy extends FilePersistenceStrategy {
     public CustomeFilePersistenceStrategy(File baseDirectory) {
      super(baseDirectory);
     }

    @Override
    protected String getName(final Object key){
        //put desired file naming logic
        return "CustomFile.xml";
    }
}

Then the usage could be:

 PersistenceStrategy strategy = 
               new CustomeFilePersistenceStrategy(new File("C:\workingTemp"));

 List list = new XmlArrayList(strategy);

Which should generate CustomFile.xml in the output folder.
