This isn’t really a BIND or DNS problem. There is not a standard way to do this.
If you’re going for some kind of automation or orchestration of these services, there are a bunch of different places to build this in, depending on the tools you are using. You did mention ISC DHCP. One approach would be to use the server-side hooks when a lease is created or renewed. You could add a script that creates what ever additional names you want.
