Custom display for each product - shop page

Hello,

I am a photographer and just built a new website on SquareSpace.

But in my shop page, where I sell posters, I can only choose one display (aspect ratio) for every article, where I'd like to customize it for each product depending on whether it's a portrait picture or landscape one or square one and so on... And same thing once you clicked on the article to show the details, if you change the aspect ratio for one article it applies to every article...

To show you an exemple you can check this page https://www.evanranft.com/store from Evan Ranft, where there are vertical, horizontal and square products, all displayed entirely and not cropped because of the ratio.

I hope it's clear enough and that someone will be able to help !

Thank you in advance !
