Lens plate with additional 1/4" 20 thread

I looked at alot different lens plates but couldn't find one that also has a additional 1/4" 20 thread - even the generic one.
I'm using the Black Rapid strap with the 70-200 and prefer to have a plate with an extra thread so I can remove the strap and put it on monopod or whatnot without having to remove/put on the plate every time.

Anyone knows if there's one out there? Generic is fine.

RRS has at least one, if you're into the A-S standard. Might have to play with where you can actually clamp the lens. Or you could just get a clamp to mount to your BR strap, and release the clamp, move the lens to the mono/tripod and lock it down.
