If you've managed to add this yourself through the source coude perhaps you could wrap it up in a .dll and make a plugin out of it.
I think (and I may be wrong) that, at present, you can only add plugins to the Adjustments or Effects menu's - and this would probably sit better in the Edit menu.
Just a thought, though I'm not a programmer and have no idea if it's even possible to create such a plugin.
I'm 95% sure it's not, but perhaps we shall wait for the final word from BoltBait and/or Rick.
