New FBX Exporter in 2017.2

I’m asking this here because I’m getting desperate.

I’ve been struggling with the fact that the model importer creates gameobjects with scale values not equal to 1 if the FBX was not exported with the correct unit measurements.
I have made a thread about this here and not having the scale values of 1 can have annoying consequences, like here amongst other things.

This can be fixed by re-creating a new FBX asset with the correct unit measurements. However when you need to change a large amount of fbx files, it’s really problematic to do it one by one.

Is there a way to change an FBX’s file scale in Unity?
or to somehow modify the transforms of the gameobjects so that they are equal to 1?

Any help is greatly appreciated.
