Hello, everyone. I import the services of the bank and test it in the postman. Sometimes they update the services and I import the yml file again from their web site. In the old version I created environmet file and there are places where I put the values ​​in the file in the services. I have to do the same thing the new one. Is there any way I can merge the old collection with the new one instead of doing this one by one? How can I integrate the structure I edited in the old collection into the new collection?

I search about this subject what the solution, is there any way merge them ect. And I think that maybe Postman Apı is the solution my problem. But I'm not sure so I want to ask anyway
