remove "product" from url

[Reifsitas]

basically at this moment the url link goes

store.com/collections/Collection123/products/product123

where as the products part takes you back to all product where i rather be taken back only to the products of the selected collection. if this makes sense. how can I do this. 

This issue affects my breadcrumbs tabs which basically goes home>>products>>product123

which leads to all products when clicking products 

rather than home>>collections>>collection123>>product123 which would take you to the parent collection of that product .
