Not that I've ever heard of. And as far as I know, CZ hasn't make an ambi-decocker model.
And if you think about it, its really a relatively unimportant addition (unlike an ambi safety...) and I doubt we'll see one, anytime soon.
Unimportant? When decocking, you're through, you're ready to put the weapon away, and you can use your other hand, with risk, etc. There's no real reason that it HAS to be your strong hand that works the decocking lever.
