Update multiple dataentries

I'd like to update the values Supported Current Rel, Firmware OpenWrt Install URL and Firmware OpenWrt Upgrade URL for all x86_64 devices.

Can this be done automatically/via a script? Since x86_64 images are generic anyway they could be bumped with every release.

That's only 9 dataentries that need to be updated... I would do this manually.
Once they are on the latest OpenWrt release (18.06.1), they will be updated automatically via script when the next release is available.

OK, done.
I didn't know there's already a script in place for that.
