How to make layer animations in a level sequence ?


I want to apply an animation for each bone in level sequence.
I know that it is possible to synthesize animations masked by AnimationBP.
However, Animation BP cannot be thrown directly into the Level Sequence.

We can add key to switch the “Animation Mode” in the Level Sequence.
but, the contents of the “Anim class” cannot be specified from the level sequence.
If we want to change animation classes of model from a level sequence, we may need to use event notifications, isn’t it ?

I want to find the easiest way for designers to use it.
It’s the best to switch exactly as we put it in the level sequence, with less use of scripts and event notifications.

Does anyone have this solution ?
Do we put the several models with different Animation Class into the sequence and switch the visibility of them ?
