Threads with no replays !

I need help to make a button or (sort order) in the Forums that display me Threads with no replays. This is for Users that can see there are no replays on Thread to a better help.

In the Picture you can see what i meen !
I need a extra Sort order, see it at the picture button.
This new Sort-order Sort the Threadbits so that they will display only Threads that have no replays, see it in the top of the picture !

Thats all

A combination of Replies and Ascending gives you that result.
