Binding Collection Lists to Specific Ecommerce Product Pages

I’m using collection lists - and I have a number of “albums” (set up as “products”) in the Ecommerce tab. When I bind a collection list to a field, it forces all my ecommerce pages to share that same collections list and doesn’t let me individualize one collection-list per product. I don’t understand why this is behaving this way. How can I bind a specific collection list to a specific ecommerce product?
