How can i mod the new black ops zombie maps without a Jtag offline ?

I know how to mod kino and five with a GPD. But how do you mod the new maps without a jtag? Is there a new way yet? Is there a way to mod the title update that would let you use GPDs for the new maps with modio?

And please don't say dont do it, because its all OFFLINE. Its all for fun.
