Triangulation soon at 23andMe?

One of the DNA accounts I manage at 23andMe finally received notice to update in preparation for the transition to the new website format, which has been promised for over six months.  The main function of updating the account is to complete a new survey on ancestry and confirm access to health results.

A new feature that I do not have access to is viewing relatives in common with other relatives and whether or not all three parties share on the same segment of DNA or different segments.  This triangulation is necessary to assign areas of one's genome to the proper contributing ancestor, so I would really like to be able to start using this tool.  (Read here for an explanation of how I did this with ancestors from Morris County, New Jersey.)
