In the anim viewer, is it possible to play a montage on an attached skeletal mesh?

I have a custom notify in the character animation, which plays a montage on an attached mesh. It works in game, but I would like to see the attached mesh animate in the anim viewer.

I am looking at this related question: Access mesh component of a socket preview asset. But it looks like my use case is not supported: A skeletal mesh asset attached to a socket on the debug skeleton has no SkeletalMeshComponent on which to play montages.

Is there a way?
