Is it possible to automatically update the size of an animation clip within a montage after reimporting that animation clip?

I have created an animation montage with several animation clips and sections in it. If I change the length of any of the animation clips contained in the montage and reimport the clip again in Unreal it looks like the size of the animation clip is not updated in the montage and I need to manually remove the animation clip and add it again to the montage. Is it possible to make this process automatically?
