Shopify Markets - Any update about integration?

Hi team, we are managing 8 different stores using Shopify and we are going to migrate to Shopify Stores.

There is not any updated information about this kind of integration, new functionalities, etc…

For example, could we keep our 8 Klaviyo accounts) Will we need to manage just one account using 8 different lists) How about the reporting by market? 

There is a big lack of information from Klaviyo about this issu which affects critically to many different brands.

Thank you very much
