Hi Andrea,
It looks like an interesting use case, however, this kind of dynamic segment creation is not a feature in either AA or AAM.
You will have to manually create traits and segments for those specific product listings.
You could have a look at the AAM REST APIs or BAAAM tool documentation to create traits and segments in bulk.
Otherwise, you'll have to look into some automated ways to make use of AAM REST APIs to make calls for trait/segment creation whenever there is a new product.
Thanks,
Varun Kalra
