Could someone here make a hack where you can costumize the "days old" of a sim in CAS?

I made a sim version of my family, two adults (parents) and three teens (me and my younger sisters). My father is older than my mother (nearly elder) while I'm older then my sisters and it feels a little weird... (you know, like your triplets or adopted at the same time or somethin like that, you know) so please good people of MTS2, can you make a hack where you can costumize how many days old your sim is? Thank you :D

PS: I'm currently working on my latest upload (really my first)...

That's easy enough to do once you get on the lot using the InSIMenator (which can be found on the Most Wanted Hacks page at the Content List, linked in my signature).
