How to reuse enum across Argo workflow templates?

Question

Say I have a parameter with a big enum:

# yaml-language-server: $schema=https://raw.githubusercontent.com/argoproj/argo-workflows/v3.4.13/api/jsonschema/schema.json

apiVersion: argoproj.io/v1alpha1
kind: WorkflowTemplate
metadata:
  name: time-zone-parameter
spec:
  arguments:
    parameters:
      - name: time-zone
        description: Time zone
        enum:
          - 'Africa/Abidjan'
          - …

Is it possible to reuse this enum in another WorkflowTemplate? I'd rather not have to copy and paste it all over the place.

Assuming it's a helm template you could do something like

# chart/templates/_helpers.tpl
{{- define "timeZoneEnum" -}}
enum:
  - 'Africa/Abidjan'
  - …
{{- end -}}


# chart/templates/$your-argo-template-workflow.yaml
apiVersion: argoproj.io/v1alpha1
kind: WorkflowTemplate
metadata:
  name: time-zone-parameter
spec:
  arguments:
    parameters:
      - name: time-zone
        description: Time zone
{{ include "timeZoneEnum" . | indent 8 }}
