VA01 user exit at line item with partner address

I need a user exit for VA01 that is at the line item level. The catch is I also need access to the partner address data. I have found userexit_pricing_prepare_tkomk (include MV45AFZZ) but that doesn't give you the "instance" address information (the address data that is specific to that order, after being changed). It only gives you the address number for the partner's default address.

Does anybody know if such an exit exists?

Regards,

Aaron
