Slack: customize notification color

[tibo43]

Hello,

Is it a plan to customize the slack notification color ?
As the title or the text, we can use a template to customize the color.

Something like that:

      {{ define "slack.color" -}}
        {{- if ne .Status "firing" -}}
          #15b800
        {{- else if eq .CommonLabels.severity "critical" -}}
          #eb3434
        {{- else if eq .CommonLabels.severity "warning" -}}
          #ffb700
        {{- end -}}
      {{- end }}

If a template is not created, the system fallback on the default color.

What do you think ?

Cheers
