Hey there. Author of the Advanced Bestiary files here.
You would have to make a clone of the Winter Wolf in the editor under "Race/Clone."
Just so you know, the process of making a clone is fairly complex. Here is a crude outline:
1) Select the race you are cloning. You can set this tag manually (CloneOf.XXX where XXX is the id of the race you are cloning).
2) You need to bootstrap all abilities that the target race has directly to the clone (including abilities granted by type, subtype, etc.).
3) Make sure each ability has the proper SpecSource and other tags specific to clones (CloneFeat, BodyLoc, etc.).
4) The tricky part is making sure you have the correct bootstrap conditions on each thing. The conditions
must be at First/120 (or First/110 for subtypes and some others). There are different conditions for abilities, spell-like abilities, resistances, languages, feats, and senses. They can also depend on type and subtype.
FYI, Clones also use the thing cnGRRacSkB for racial skill bonuses (use the Target tag for the skill, abValue for the value, abText if it is situational).
Steps 3 & 4 are critically important to do correctly. The various clone scripts depend on proper tagging and bootstrapping conditions.
5) Make sure you fill out the other fields explicitly as well (CR, # arms, # legs, space, reach)
As with anything, look at some of the other clones in the editor to see what you need.
BTW, I quickly coded up a winter wolf clone and attached it. I haven't tested it, but feel free to use and examine as you please. For your info, here is the raw XML
Code:
<thing id="clnxWinter" name="Winter Wolf" description="Winter wolves are larger, smarter, more ferocious variants of worgs with white fur and a deadly breath weapon.\n\nA typical winter wolf is 8 feet long, stands 4-1/2 feet tall at the shoulder, and weighs about 450 pounds. Winter wolves will often ally themselves with frost giants, hill giants, and other large humanoids, serving entire tribes of giants as both scouts and guards." compset="GRClone">

FYI, clones may be changing. I am working with the powers that be at Lone Wolf to transition to the polymorph routines for the templates that take abilities from other creatures (Amalgam, Consuming, etc.). However, this is complicated and will probably involve using gizmos and making new UI elements, so it will take me a while.
