Active Directory Security Group membership based on specific attribute

Trying to figure out if there's a way to create an AD security group and populate its members with user objects that have a specific attribute.

Example:

ABC Security Group

User XYZ has attribute countryCode = 0

User CDE has attribute countryCode = 1

User FGH has attribute countryCode = 1

I want to populate ABC Security Group with all the users who have attribute countryCode = 1, automatically

The idea  is that I've got thousands of users with countryCode = 1 and I really don't want to have to add them, or remove them, manually.  I would like if their countryCode ever changes from 0 to 1 or 1 to 0, it will automatically add or remove them from ABC Security Group.

Thanks,

Daniel
