XF 1.4 How to put another members name under thread avatar?


Active member
I want to to be able to add a field in member profile settings that they can put a users name into that is a registered member on the site then have that name show up under the persons profile name in the thread / post view where if someone clicks their name it loads their profile.

basically I want a way for people to list someone on site as being in a relationship with that person. What's the best way to go about this in settings on xenforo please.
