Blendshape name in Unity importing wrong

I am importing an fbx made in maya with simple blendshape on it but it's got the wrong name when I set it up in unity. In maya, for example, the blendshape node is Blade_Longer, and the target shape is Dagger_Low, now I export the fbx and bring into Unity...but the blendshape in unity is called Blade_Longer.Dagger_Low How do I remove the secondary name of the object and the period? I just want the blendshape to appear as Blade_Longer and that's it
