Hey,
Now I see what you mean.
I think what yo want is already possible for floats, by using the clip under “NodeCanvas/Set Blackboard Variable Float”. This clip is able to animate a float variable by keying it like normal. This clip is available in the NodeCanvas – Slate downloadable extension.
Please check it out and let me know if that is what you mean. If so, I can add more similar clip for more types 🙂
