Assign a configuration to a specific device or group of devices

The conditional configuration is a great feature when they are using your router. I would like to know if there is a way to assign a device name and a generic configuration ID - so that I can reassign devices from the NextDNS web-site. For example, a DNS name like <device>-<generic account id>.nextdns.io and then on your web-site, I would like to be able to map <device> to <configuration id>

This would be super helpful for being able to:

1) Reconfigure devices when they are not on my router (i.e. a mobile phone)

2) If I want to move my device into the same configuration as another device for testing the impact of rules on different devices

3) Being able to temporarily block/unblock specific sites for individual devices - and the moving them back to their original configuration without a router or device configuration change.

Would something like this be possible?
