Hi,
Should should be able to do this via Routing policies using Route Maps, in the Route map you will match data to a criteria ( access list, interface ) and if it does match, set other criteria such as exit interface etc.
Below is a small example, but route maps are extremly dynamic and should sort you out.
route-map test, permit, sequence 10
Match clauses:
interface FastEthernet0/2
Set clauses:
interface FastEthernet0/2
Policy routing matches: 0 packets, 0 bytes
route-map test, permit, sequence 20
Match clauses:
interface FastEthernet0/3
Set clauses:
interface FastEthernet0/4
Policy routing matches: 0 packets, 0 bytes
