howto configure DHCP to reject renewal of lease

What I'm trying to achieve is to configure the ISC dhcpd to give the client
(when it tries to renew its lease @T/2) a new IP address - to avoid having
the same IP for a long time.
So, let's say: client1 is given IP1 for 1 day, after 0.5 days client1 will
ask dhcpd to renew its lease - i want the dhcpd to tell him DHCPNAK - you're
not allowed to renew your lease. This would force client1 to send a
DHCPDISCOVER message again and ask for a new IP
Is this functionality available in v3.0.4 of the ISC dhcpd?
