Is there a way to Scale Root Motion with the model?

When i scale my model my root motion from animations doesnt scale with them. So the giant model will walk at a snails pace or the tiny models will move superfast.

Is there a way to get the root motions to scale with the model? It doesn't need to be at runtime, but I can't edit the FBX Files to make the models bigger before import, they need to be scaled in unity somehow.
