Updating existing collections from APIs

I have created my first API - and I was learning a lot about OAS 3 at the same time. I found that I kept making mistakes, but it wouldn’t be until I created the collection I would notice it.
The problem is I needed to keep creating new collections. Is there not way to update an existing collection?

If not am I doing the process wrong, as it seems clunky.

Hey @tank104,

You’re not missing anything! This is a reasonable request, and it’s currently being tracked here: https://github.com/postmanlabs/postman-app-support/issues/6722.
