Hi Jeff and welcome to the forum.
PB has no "intelligent" links in the manner you describe. If you search the forum you will find several posts proposing improvements to the way in which links are currently implemented, such as making them directional. For the time being you will have to create the relationships you require between nodes ("Thoughts") by using link Types (Core and Pro Editions), or by inserting an additional thought between two thoughts to carry the extra information needed about the relationship. Remember that PB allows only one direct link (of any kind - parent, child or jump) between any two thoughts.
