How can I inject an environment variable into config.deployment.targets?

Hello Hugo Fans! Thanks for a great tool. :slight_smile: Can someone suggest a way for me to get an operating system environment variable injected into config.deployment.targets[0].url?

Or should I create a feature request to have a non-slice version of this configuration? I have so much logic in my config.deployment.matchers that I’d like to not have to templatize the entire ./config/_default/deployment.json file… thanks in advance!
