Populate ALL Items from ALL Collections on a CMS Collections Template

Hey guys,

I created a CMS Collections page where I have a filter on the left to populate the items based on Collection, see below:
https://lanna-lashes.webflow.io/collection/tweezers

However, if you click “all-products” nothing shows because I can only link each item to one collection. Is there any way to make the “all products” link just populate ALL items from ALL collections?

Thanks

P.S. if you’re wondering why I’m creating products through CMS and not Ecommerce, it’s cause I’m in the process of connecting my payments to Foxy.io
