I have a section 'people' which has several related entries such as 'sibling', 'spouse', 'offspring', etc. When creating a new 'person' the user has to set up these relationships. I understand that's it's possible to easily look up a persons relations in either direction as per http://buildwithcraft.com/docs/relations.
However, is it possible to reflect this in the CMS? So, when a person is related to another via 'spouse' it shows up for both people automatically? Currently, the user would have to do this manually.
