Does FAME allow to create one-to-one relationship with automatic update of the back links? So far, I have seen two entities FMMultivalueLink (one-to-many) and FMMultiMultivalueLink (many-to-many) and their examples. 

I have an elements and its behavior in separate entities and I would like to  create and update one-to-one links between these two entities. I haven't found any example in Moose.
