How to clear the stack except the bottom-most scene and then push (with animation)?

### Question

Suppose I have a group of scenes A, B, C, D under the root scene, scene A is initial.

The current navigation stack is A -> B -> C.

I wish to show scene D with a push animation, but at the same time silently reset the whole stack except the initial scene A, so that the stack becomes A -> D.

What I tried:

1. A sequence of `Actions.popTo('A')` and `Actions.push('D')` - looks weird, like a card deck going off the table, also the pop and push animations are sometimes mixed.
2. A sequence of `Actions.reset('A')` and `Actions.push('D')` - no animation at all. Even though push is animated when called on its own.

I just want to see a push transition into scene D, but at the same time to silently get rid of A+B in the stack.

Is this even possible?
