Waitlist issue

Site URL: https://melikecarr.com

I'm wondering if I might be missing something with the waitlist function or if this is a limitation: I am seeing waitlist sign-ups just fine but there is seemingly no way for me to navigate to the listing so that I can see which items people are requesting. I have a lot of products with the same name (like "incense holder") and was hoping to use the waitlist as a way to see which ones people were mostly interested in so I can make them accordingly. Is there something that I'm missing or do I need to have unique item names? Thanks in advance!
