Merge definitions from subsequent (swagger) imports from url


I’m using Postman to test an API that I’m building.
The API gets new endpoints quite daily and I’m importing them from swagger/open api definitions exported via an url.
The problem is that I can’t merge the existing tests, with data, parameters sets, with the new ones, so I end up having several collections, which makes it very difficult to maintain and automate.
A button “Update collection” would be nice, that would merge the existing collection with new stuff that comes from the server.
It could compare the 2 swagger documents, import only what’s new, preserve the old calls.
If I change the API signature of an existing method, it’s easy to just manually remove or add a parameter or value.
