Organizing custom posts types hyerarchically (More types)

What I want to do is to organize my custom type posts into a parent/child relationship.
I want all the posts of custom type “boy” to be child of another post of custom type “father”. ALso, when creating a post of custom type “boy” I want to have a select option with all the posts of type “father” to choose from, in order to set it as parent of current post.

It would be nice, if possible, when accessing a post of type “father” to be able to see all the posts of type “boy” assigned as children of it, and have he possibility to bind/unbind them.

¿Is this posible? ¿Does enyone know if there is another workaround tu achieve this functionality?

Many thanks in advance!
