If you're running just one CAS I don't know a way, however if you have more than one CAS I'd do it like this:

Group the VLANs based on desired gateway on each CAS. Place the trusted interface for each CAS in a VLAN built with the desired gateway. But it sounds like you want to route the VLANs on the actual CAS. I wonder if you set "pass through VLAN ID to managed network" if you could then route the data based on the VLAN tagging.

How about Option C?

VLAN 1,3, and 5 goto router 192.1.1.1 routes out over one ISP
VLAN 2,4, and 6 goto router 192.2.2.2  (example IP's) routes out over
another ISP
