[Q] How to extract an individual device's config from backup?

I’m sure we’ve all experienced it, all devices work fine then one stops, or a device works properly only to stop after a network rebuild.

Is there a way to copy the device config from a working or back-up installation onto a new one?

To clarify my inquiry here are a couple scenarios…

Meter Switch 2 (out of 4) works fine, after network rebuild only the other 3 work…
You spend ages getting a finicky device to work right only for it to later stop randomly or after rebuild.

We dont always want to restore a whole backup to fix a single node.

Is there a way to manually extract & restore individual z-wave device configuration from a backup?
If not could you make a useable backup while the specific device’s functional install is alive?
