From switch VLAN want to go out Comcast ISP

Is it possible to router specific IP segment traffice to a designated outside interface?  I can not find a reference to this.  Thanks.

You just need to put default routes in the router for both.  Then make access lists permitting those ranges out the required interface.

Yes. It's called Policy Based Routing (PBR). Below is an example of how to do it.

access-list 1 permit    ! vlan 1
access-list 2 permit ! vlan 2

route-map homer permit 10
 match ip address 1
 set ip next-hop ! Comcast next hop
route-map homer permit 20
 match ip address 2
 set ip next-hop ! Verizon next hop

interface FastEthernet0/0
 ip policy route-map homer
