Webflow needs the ability to create multiple collections with the same URL :o
One example, why:
On InLearnity Favorites I have two connected collections: results & tags.
A results can be a documentary, a book, a meetup, a talk and much more. A very diverse range of categories with quite some different fields. The user should not have to think about the category, but having a simple to understand structure like http://inlearnity.com/result/selma
This is why currently I have one collection for all categories - including a lot of "IF category XY" sections. And because of the maximum limit of 30 sections inside a collection I can not embed additional details.
Having one collection for documentaries, one for books, one for talks and so on, all with the /result/ URL would solve this problem. And I am absolutely sure there are a lot of other use cases as well.
