Different Meta Titles and Meta Description for each Shopify Market

[michelle_nz]

Hello all, 

I currently have a store with Shopify that uses multiple Shopify Markets. Currently, my meta titles reference my main market, for example: Purple glitter eyeshadow | Long-lasting | Brand New Zealand. When a customer is viewing from a country outside New Zealand, such as the United States, I would like the meta title to be Purple glitter eyeshadow | Long-lasting | Brand United States. 

Is this possible to do in the theme.liquid file? Or using metafields? Or an app? I have seen similar examples using localization.country.iso_code to change pieces of the body copy, but I can't determine the right code to change the meta titles. 

I appreciate any help you can provide!
