Expand/collapse all twisties in Outliner

Hi there,
I don’t know if this is possible in the beta, but is there a way to expand or collapse everything at once in the Outliner mode? I have multiple layers in my hierarchy and it is a lot of clicking to open or close every twisty. I apologize if this is something easy I missed.
Thanks
Jessica
