Advanced family tree options!

[SimDad2004]

In TS3 I would like the option to select a neighbourhood family and add them to my family tree as a relitive, this is because I have made my own familiy before then added my sisters family and cousins etc, but they were not related in the game because I didnt go back to the root and create them as they were born, if you get me? Like I didnt start with my grand parents, the give birth to my mum and her siblings, neither did I do it for my dad.........

this has always bugged me a little.... so to be able to add a relationship would be cool...
