Connected Relations (husband/wife)

I strongly suppose that something like that is already planned:

Let's assume I want to add the married couple "Albert" and "Bella" to the Persons Collection and fill out their individual profiles.
I've already added the Relations "Husband" and "Wife" to the Profile.

OK, first I fill out "Albert's" profile. In the Relation "Wife" I chose his beloved "Bella".
Next, I want to fill out "Bella's" Profile.

-- What I clearly want at this point, is that after the already made first connection, Bella's profile should in the Property "Husband" already have the logically needed entry "Albert".

Both Relations (Husband and Wife) are a pair. If the user fills out one of them, the other should automatically do the mirrored thing.
