Summary

It'd be really cool if you could use the environment variables in the collection properties.

Why should this be worked on?

My use case is that I have a collection with a bunch of folders for my work. All of them authenticate in the same way, so instead of having to setup the authorization for all of them. I would like to only set it for the entire collection.
