How to create blendspace in C++?

Hi, I want to create blendspace in C++ and place animation in the blendspace in C++.
Could you give me any tips/advices?

You could start here: UBlendSpace | Unreal Engine Documentation

Apparently you can customize its creation: FObjectInitializer | Unreal Engine Documentation I assume you could manually add the blend points and anim using that.

But may I ask why? It seems rather involved, and I can’t really see the value of being able to dynamically configure the blend space.
