Over the years our business has changed, and for currency conversion reasons, it would be advantageous to switch our account from US dollars to Canadians.
I realize that it is not possible to do it automatically. However we do a lot of business with them, and I wonder if that has any weight, to get them to do a manual database tweak to change the currency on our account; or switch our historic quality score over to a new account.
Google does amazing stuff, it's a shame that they haven't implemented multiple currency management.
