Clarity on selling at Amazon South Africa.

I’m a seller on Amazon in India, UAE AND US ; and now want to expand into South Africa. What’s the right way to do this? As in my seller central (under add marketplaces) I can’t find an option of South Africa. Maybe I can create a new account on ‘Amazon seller central South Africa’ , but in that case would my two accounts be able to merge ?

This is quite important for me as I want to have the same listings functioning in every country

Kindly suggest. TIA.
