Sugestion for DHCP

I have a sugestion for option that I desperately need.. I have 2 gateways (postpaid a nd prepaid). I use Mikrotik as postpaid and some other as prepaid. Mikrotik is 10.10.0.2 and the other one is 10.10.0.5. Is it possible to make an option in DHCP server; I reserve IP and he will be static and he will send to another gateway. That would be a option with who will I dictate for some MAC address have IP 10.10.1.111 and that the gateway and dns are 10.10.0.5. And that to all other nonreserved and nonstatical gives 10.10.0.2 as it should do Right now that’s working at me, only as DHCP I use some different computer on which winroute is DHCP and he has that option.
