Instance settings for environments

[davinishi]

Something I never seen on any client is a parameter settting for multiple instances environments.

E.g:
Some companies have multiple instances running for each system: development, preproduction, prouction, etc.
Today, the standard environment variables allow us to set different URL's, usernames, passwords, etc, though we have to create one
environment for each instance, in this example, 3 environments at least, each environment with the same amount of variables with different values corresponding to the correct instance of the server.

Idea: Instead of having the conventional Environment Variables, it could be easier if a dynamic variable could have multiple values, so when setting the active Environment, we could set also a second parameter like "Instance".

The configuration would look like this but of course there are better ui than that:
