nimbus hi top saddle with handle?

can the kris holm tour bar handle be configured onto the nimbus hi top saddle?
i ordered this saddle but then realized i may not be able to attach a handle.

You could contact UDC and ask them to be sure but looking at the photos of the underside of the saddle it looks to use the pre-2009 Velo base, which would make it incompatible with the T-bar handle.
