Per Axis LookAtBone Clamp & Visualization

Hello,

I have some quick questions using animation blueprint;
-Is it possible to have a different clamp ranges, for each axis into the lookat node, instead of one float for all axis. Should I use multiple lookAt for each axis to achieve what I want?
-Also, how visualize angles like at this moment in this video?

-And a more complex question because situational, I’m doing a animation where the head of a character folow a target, and use multiple lookat bone for that, starting with the base spine to the head, with progressive alpha weight for each bone for a smoother result. So the whole upper body move to make the head looking the target point. I’m looking for an animation blueprint which move the head in priority, then the body if necessary (if the head is in an angle limit). Is there any thing made to do that or should I make my own system?

Thanks.
