Anything change with tethered feature in CP21? Desperately hope so...

I have a Nikon Z7 and shoot tethered to an Apple laptop. I have CP20 and there is no ability in CP20 to shoot images to the Z7's in-camera card and to the computer hard drive at the same time, something I want to do for instant back-up purposes.

Does the new CP21 have the ability to do this?

I've put forth this as a request as pretty much every photographer I know who uses CP wants this feature, I mean, why would a photographer not want this instant back-up safety net facility and why don't CP simply implement it?

From what I can gather, with CP20 there is no easy way of having an instant back-up when tethering, not without having some expensive external hard drive array, an add-on third party piece of software and a degree in computer programming to set it up, even then it does not back-up with each shot like the aforementioned simple method would.

Now I have a Z7, which only has one card slot this is more important to me than ever, before I would avoid tethering and just shoot to the two cards in my old EOS 5D MK4. Now I'm all out of solutions, at least a simple one.
