unreal 4 – Is it possible to create assets from blueprint in UE4?

What I’m trying to do is a Blueprint Utility tool that let me create a Animation Sequence asset to save the current Pose Snapshot of a skeletal mesh.

I see there’s Create Asset node from Asset Tools Actor but I have no clue on how to create the factory to make it (same with Crea Asset with Dialog).

I’m currently trying by using the library: LE Extended Standard Library that provides the Engine of many Factory blueprints but whenever I try to save it, the engine crashes and I cannot investigate on the error. A possible issue could be linked to the calling context? I’m not sure about that one and I didn’t find any answer on UE4 forums.

What I would like to achive is to create an asset like this:
