Can you modify Additive Layer tracks in the AnimBP/BP?

Hello,

I want to know if you can edit the Additive Layer tracks of animation clips in the AnimBP/BP.

My animations are looking at the wrong direction, so I have being changing them manually with the Additive Layer Tracks, just rotating them 90° degrees. This will be impossible later due to the increasing number of the animations.

Thanks,
Alejandra
