Additional context
This issue was originally outlined in #147 as a part of the environment feature, but was moved as this is a feature that can be built after the first, but isn't required to have an mvp for environment configurations.

Creating this to minimize scope for #147. Will require this issue to be resolve in some way for this issue to be started

#591 resolves this, hence closing.
