Not trivial configuration of Freeradius as DHCP server

Hello! I`ve tried to configure my freeradius installation like described here http://wiki.freeradius.org/guide/dhcp-for-static-ip-allocation but it`s very simple case for only one subnet. Now we have two networks which needs to get IP by DHCP server. So is there any possibility to configure DHCP scopes for different networks? Thanks!
