ward directory

bishop asked me to find away to put a nonmembers name on the ward roster with his wife who is a member. He is listed on her information as a non member spouse. But when you look at the ward directory he is not showing up. I have checked our ward roster and found many examples that the spouse is listed with their member spouse on the ward roster. So it can be done but I can't find a way to do it. I am the Assistant Ward Clerk (membership) and have found a few things that I can not do but the Ward Clerk can. Could he be the only one that can fulfill the bishops request

You'll have to call support. Only they have access to that switch.

I would be cautious about doing that. The non-member spouse may not want to be added. This will need to be done on a case-by-case basis depending on the wishes of the couple.

I'm guessing by "roster" you mean the Directory web-app and similar tools.

Even if the non-member spouse is made visible in the directory, it's not possible to give a non-member spouse a preferred name separate from his/her regular name. When we were asked about that a couple of years ago, we learned that the best solution to that situation was for the non-member spouse to be baptized. For the particular case in my ward, the ward missionaries said they were working on that. Not many months later, they succeeded.
