Contact Hierarchy Feature in Redwood Sales?

My lead is exploring implementing a contact hierarchy within our Redwood Sales project. He stated that there was at one point in the past a Sales UI contact hierarchy, but I am not able to find if this is available in Redwood.

Is there a way to have contact hierarchies within the Redwood Sales UI? For example, being able to see and edit a tree-type view of who reports to who in a customer/account organization, similarly to the existing account hierarchy subview.

If not, is there an alternative available that would help address this requirement?
