Are lists supported in Behavior yet?

I was wondering if anyone could answer this question for me and if not when is It coming out? Thank you!!!

Clarify your question. I have no idea what your asking.

On this video, - YouTube

he mentions (3:41) that lists are not supported in behaviors yet. Is It supported now?

For those curious, you can use Data Asset or Blackboard, it seems to be the solution atm.
