I'm new to the AppSumo world and just made a single code purchase of your product. I now realize I'd like to have the features of the 4 code lifetime subscription. Do I upgrade from within the AppSumo website or the Branalyzer website, and since I've already purchased 1 code, is there anything I need to do on my end to ensure when I purchase the additional 3 codes it will combine my previous purchase?

Thank you.
