Contact.Address Field and Contract.Country_id

Summary:

We have a design to route incidents based on the Country of our contacts. We are trying to determine which contacts have a NULL country value.

In our workspace we have contact.Addr which brings in all the various contact addresses fields. But this is not a field that can be used in bz rules or reports. I also see the field contacts.Country_id but this is not available to bring into the workspace or reports?

For some reason we do have a custom field contact.C$country but this only populates once, so we can have a different country listed in contact_country_id and contact.C$country
