Reference config parameters in other parameters

[laur1s]

Hi,

I'm sorry if this has been answered before but I haven't managed to find it.

I want to reference a value of a parameter inside other parametrs in config.yaml. What's the way of doing that? Example:

template_path: s3.yaml
parameters:
  Application: lau
  Environment: {{ stack_group_config.Environment }}

stack_tags:
  Environment: {{ stack_group_config.Environment }}
  Tier: "S3"
  Name: "{{parameters.Applicaion}}-{{ stack_group_config.Environment }}--S3-BUCKET"

Is this currently supported? Perhaps I could use some workaround to avoid specifying the same value multiple times. Thanks!
