Cadians List with Elysian allies

[Canefire]

I am trying to add Elysian guard to my Cadian army list as allies. So far I can only use the Elysians as regular guard self allied. How do I get the Elysian rules to show up for the allied unit? Thanks for any help here.

Now that the first Horus Heresy is in the files, I'm headed towards the overhaul of the IG regiments compatible with the new allies.

Thanks Homer. I will watch for an IG update.
