Conditions in env vars

[DeedsBaron]

Hi im really confused and stucked. If there any possibility to make dynamic collection envs, depending on some value in global env?

{
"local_base_url": "localbaseval",
"staging_base_url": "stgbaseval",
"prod_base_url": "baseval",
"base_url": "switch (_.env) case local: return local_base_url ...."
}
I mean something like this, tried to make template tag plugin, but cant get collection env values from there only can get global :(((((((
