Modifying FBX animation import settings to ignore translation or scale

Hi,

I'm currently working on a project that has multiple humanoid characters. I am trying to standardize all of their animations to the same animation assets. I am looking for a way to import FBX files from Max and only importing rotational values, removing/ignoring any translation or scale values that with break characters with different rigs. Are there any import settings in Unity that already support this feature? If not, does anyone know of a scripts/resources that would support this?
