Wrong root node from separated anmation fbx model.

Hi!

When I import my animation from a separate (bone only) fbx model, Unity looks at the first bone as a root object and thus has a different structure of bones than my character bones. (Unity it creates a new empty GameObject root, when the fbx model has a multiple objects which are not in contact (in hierarchy) with each other. Like my character, bone and mesh.) So, sadly in this way, the animation does not work (Unity not found the root_bone (main bone)). Someone has a solution for this?

Here is an image of the two different structures.
