Hi!
Yes, you're right, households can have the same name...
I've tried your v2 and everything seems to be ok... Clicking on a house you can decide wether if you want to age that lot or not.
Wonderful work! Thanks! 

Thanks for sharing with us! I think your hack could be very useful!
However... Do you think it could be possible to extend "suspend/resume aging" to an entire household instead of a single sim?
This way could be much more simple to keep control of aging in neighborhoods...
It was only an idea 

Thanks a lot!
