workflow metadata not available within step

[santhosh60]

The step 'dump' has access to only the metadata 'foo' which is declared at the step level and does not have access to 'fizz' which is declared at the workflow level.
is it supported and if so please guide me in accessing the metadata at the workflow level from the go templates defined in a step command.

input:

version: 1
metadata:
  fizz: buzz
steps:
  - name: dump
    metadata:
      foo: bar
    command: "echo {{ index .Metadata }}"

output:
