Seems like it would be a fairly straight forward operation, and it looked like it was in 2009 and in 2011, but in 2010 they changed up the way FBFbxManager() works a bit so I’m a little confused on how to do this.
Edit: Solved.
FBFbxManager().LoadBegin(pMerge=True)
FBFbxManager().ModelsAnimations=True
