I haven't come across this feature in other tools, to be honest.

The access token and cookies I use for multiple APIs have a short lifetime, expiring within a few hours. If there are numerous interactions, replacing one by one in every request can be a time-consuming and painful process.

I think it would be helpful to have a simple method to easily override a specific header property, such as Authorization, for all requests in a specific folder or multiple folders which are not nested. This would make my work much easier. I might call it Session UI since it's not specifically related to environment variables that I hardly ever change.
