flow from jit.matrix A to jit.matrix B, but ignore plane X from jit.matrix A

...if that makes sense? :)
In other words, I have stuff going on already in plane X in matrix B. Now I want to add to that everything from matrix A except its plane X.
I think I can do this with jit.op, but I would have to pass both matrices A and B through it and create a third matrix C.
Is there a way I can do it without having to create a third matrix?
