How do I identify the market origin of each order in my multi-market store?

Hi guys, i have store with 4 different markets (AT,DE,SK,IT). Im selling digital products fullfilled manually one by one and my question is how i recognize wich order came from wich market?

Because im sending product via email in multiple languages but i cant find filter for those.

Also want to see statistics for different markets more deeper then in Setting>Markets>Market analysis because there are only 4 columns

Thanks
