I followed the Setting up ExternalDNS for Services on AWS tutorial. I want to have multiple continent in my ingress but it support one.

external-dns.alpha.kubernetes.io/hostname: example.com
external-dns.alpha.kubernetes.io/set-identifier: example
external-dns.alpha.kubernetes.io/aws-geolocation-continent-code: "EU"

For one continent it works fine, but I want to add Asia too.

How can I add multiple continent in one ingress?
