Welcome to the community
In an attempt for all the feature requests raised here to not get lost and for the best chance of it reaching the team - Can you submit these via the Github Issue Tracker please.
I did a quick search on there and found one that looked similar if this is what you’re after, you can upvote this or add additional context for your use case.
As an alternative way to make changes to the environment variables, you could use the
Find and Replace feature within the app. This searches across all the different areas so it might be a way to speed up your process.
I created a gif of me changing the value of a previously set variable and sent a new request using this value, all without going anywhere near the manage environments feature
It’s a very basic example but hopefully, it might give you a slightly quicker way to change the values.
