Where? On the same box as the dhcp server?
Please supply some basic information about your network - eg, routing,
servers, gateways, subnets, and the *reason*/mechanism that gateways
change, client OS and config.

Easy - but, um, not practical. You would need to make the "client" query
the server at ludicrous intervals by using 1 second leases. Your
proposed solution is based on the flawed premise that the "client" is
always listening for updates from the server.

Would you settle for alternative ways to achieve the desired outcome?

If you can supply more information a suitable method can be proposed.
