Seam3 @ViewConfig and pretty-faces mapping id

Question

How can I get id of urlMapping when using pretty faces through the Seam3 @ViewConfig interface?

In pretty-config.xml id is specified on url-mapping element.

<url-mapping id="foo">
   <pattern value="/page/foo/">
   <view-id value="..." /> 
</url-mapping>

With @URLMapping annotation provided by Pretty Faces i can use id attribute.

@URLMapping(id = "foo", pattern = "/page/foo", viewId = "...")
public class FooBean {
    // some code here
}

But @UrlMapping annotation provided by Seam faces doesn't have any id attribute so I wonder what will be id of this mapping.

@ViewConfig
public interface PagesConfig {
   static enum Pages {
        @ViewPattern("...")
        @UrlMapping(pattern = "/page/foo")
        FOO,
    }

    static enum AnotherPages {
        @ViewPattern("...")
        @UrlMapping(pattern = "/page/foo2")
        FOO,
    }
}
