Multiple iSCSI vSwitches

I currently have vSwitch2 setup with two iSCSI ports for my main iSCSI traffic.  I've got another SAN for a testing environment.  I'd like to segregate this iSCSI traffic over a separate vSwitch.  So I created another vSwitch, port and nic.

Now when I add the ip to my Storage Adapter, how can I force it to use this other switch?  Is that possible?  Can I create multiple iSCSI software adapters?
