Thank you for reaching out to the community about that! I would be happy to look into that for you.
Would you be able to send me a screenshot of the different sizing you were hoping for? As well, was there a specific theme you were thinking about using? If you were looking at the free Shopify themes, then our design team may be able to help you with this (subject to our Design Policy). If you'd like to provide a bit more information about what you were hoping to do then I can confirm for you! Thank you.
