This is already sypported. You can specify those tags in the tracer configuration.

We're doing something like this:

config :spandex, YourTracer,
  env: :your_env,
  service: :your_service,
  service_version: :your_version,
 #....

@DReigada is there a way to use service_version based on the git commit sha instead of explicitly tagging it in the config section?
