It would be really good to have the racial subtypes for each race and to have the corresponding changes happen on their own. For example the "Elf" race has the "Savage Elf" subtype which automatically replaces the proper racial traits. This can be really usefull for more "rare" races like Tiefling where the player is able to chose from a variety of different "Tiefling Heritages". These heritages immediately affect the PC since they even have different ability scores between them.

I'm not exactly sure what is being requested here. Is there something missing, example 'Savage Elf' that should be included with a source we include?
I do know that Book of Angels (Aasimar) and Book of Fiends (Tieflings) has several racial variants and those were coded up as easy selections that applied the racial ability scores, and assigned the various traits easily.
Unable to ascertain what was being requested. Closing this out.
