Locomotion system and turn animations

I'm exploring the Locomotion system to see whether it'll be feasible to use it for a project.

One thing that the characters need is the ability to turn on the spot (e.g. to react to something behind them). The artists have provided some dedicated turn animations for this, which I'm willing to trigger from code in some way.

How do I wire these up so that the Locomotion system takes care of turning the gameObject, doing foot-planting, etc?
