Include port in environment configuration folder name

Hi Grav Community,

I read about environment configuration here:
https://learn.getgrav.org/advanced/environment-config

I try to create a specific configuration for a server running on a specific port on localhost, so I created a specific configuration in user/localhost/config/system.yaml

When I now access my site with https://localhost it reads the configuration. But when I access it with https://localhost:3000 it loads the default config.

How can I include the port to my environment folder name? ":" is not allowed in folder names.

Thank you!

Can you please create an issue here: https://github.com/getgrav/grav/issues
