Adding a second WAN subnet to a SonicWall

I have a sonicwall 2040pro with Enhanced OS.  We are in the process of upgrading our T1 from 1.5Mb to a bonded 6 Mb.  We are keeping our old IP range and they have added a second IP range to our new router.  My question is how to properly configure the WAN interface on the SonicWall.  I have read a similar question here but it was relating to the LAN side.  I've configured the new subnet as a "Secondary WAN Subnet" and assigned it to the WAN zone.  The other article mentioned adding it to the LAN subnets group (in my case I added it to the WAN zone but I don't see any way to add any address objects to either the LAN or WAN subnets group in the sonicwall).  These groups are greyed out and not modifyable according to the Sonicwall documentation.  I've also added a route  as follows:  any  "WAN secondary subnet"  any  0.0.0.0  X1

Any help is much appreciated!!

We do have a support contract.  I wasn't aware they would assist with configuration changes.  I look at that in the future.  I added one of the new IP addresses and assigned it as "Secondary WAN IP" and assigned it to X1 as well as adding the new network as "Secondary WAN Subnet" and left the route listed above.  We have cut over to the new T1 and the connection is there.  I can only see my original subnet thru www.cmyip.com but that doesn't mean they are not working.  I will test outside access inbound tonight with the new IP's and report back.  Hopefully this experience will help someone.  I'm awarding you the points.

Thanks all!
