all, Is there a way to have a listing of upgraded sites

Hi all,

Is there a way to have a listing of upgraded sites on prosites, or a payment receipt listing ?

I need to show a listing of my actual or older upgraded members for my accountancy. (I only use Paypal for upgrades)

My final goal is to know the country of each subscribers. (Because vat information)

I can see a field "pro site" on the wordpress sites listing, but i can't apply a filter on this.

Tnank you for your help.
