How to manage address heirachy in Bahmni

Hi I have a question with Address Hierarchy in Bahmni. As I read from here https://bahmni.atlassian.net/wiki/pages/viewpage.action?pageId=4915202

I’m not sure that 1.Do I have to order heirarchy like this

Address1
City_Village
Address2
Address3
County_District
StateProvince

all the time? or I can change? Actually there is no Address 3 exist in my bahmni.

  1. Can I add upper hierarchy address like Country in this order?(my hospital is at the border so there are some foreigners visit us)

  2. Can I add lower hierarchy address?

Thanks for answer
