Adding Countries to VAT Filing Services

We already use Amazon VAT Services to file VAT returns for Italy. Now we want to add Spain, Poland, Czech Republic and France. When I click on the Add Countries link, it says that I can’t add countries if one or more countries has been verified. What does this mean? Does it mean that I have to wait until the next VAT return is due? Since Italy returns are quarterly, I will need to file returns for Poland, France and Czech Republic before the next return for Italy is due.
