Customization alert_notification.html of grafana running on docker

Hi all,

i’m running my grafana setup using docker-compose.
As i am familiar with the grafana-provisioning procedure i was able to use this for provisioning dashboards and alert-notifiers on startup successfully.

The point i stuck currently is how to handle an customized alert_notification.html
Is there any other way to get this persistent without setting up an named volume for /usr/share/grafana/public/emails?
