Hello @Seller_vZ40irsUOhLKZ,

Dougal here and the answer to your question is not a simple yes or no, but I will do my best to explain why it isn't so cut and dry. I will use bullet points to consolidate space and my response, but if you want me to elaborate on anything in greater detail, please just ask. This information is also under the assumption you are referring to your Amazon Storefront and not your Display name.

1. Currently, for an Amazon Storefront, 1 store per brand (you cannot have the Brand A storefront with ASINs from brand B)
2. An overarching brand name might be a solution, but to do this all the ASINs you want to list in the store will have to have the brand name attribute as that overarching brand (basically, there wouldn't be any differentiation between any of the "sub" brands because in order for them to be in the store, they need to have that overarching brand name)
3. Another note on the overarching brand name, it is against Amazon Brand Name Policy to change the brand name of an ASIN beyond any minor typos or abbreviations. This is specifically called out in the linked policy FAQ section in the questions titled. "I’m unable to edit the ASIN brand name to correct a typo, capitalization, or legal abbreviation showing incorrectly on the Detail page." It's the 2nd to last question.

I hope that answers your question completely, please let me know if you have any other questions or need any additional info.

Best, Dougal
