How to pass Variables in Monaco Config Yaml files?

[Aditya-Sinha1990]

Topic: I have been going through a couple of discussions in the forum to find a fairly simple solution for updating config files.

Requirement:
During CD process I need to add another config line. I am looking to use variables and not having to write a new config line every time.
synthetic-monitor.yaml_.txt

config:
-customer-a: customer-template.json
-customer-b: customer-template.json

customer-a:
-name: customer-name-a

customer-b:
-name: customer-name-b
=================================Instead I am looking to acheive this in yaml file =======================

config:
-{{ configNameVariable }}: customer-template.json #<-- just one setup

{{configNameVariable}}:
-name: {{ CustomerNameVariable }}

Solutions till now:

1. write your own script to add new config lines in YAML file - preferred
2. write your own script to add new config lines in json file directly

Any ideas or use cases or workaround or links are appreciated?

This is resolved and can be closed.
Apparently, this feature is in NEW_CLI and can pass environment var as {{ .Env.configNameVariable }} in YAML as well.
Here Environment Variable is configNameVariable

Closing this Question thread as it's Resolved for me.
