What are your thoughts on adding another setting to the app that allows you to add custom text/HTML that would get injected into the default template above the variables? I like the default templates, but we always have to modify them in each alert we email out to provide a URL to additional instructions (i.e. runbook on steps to take).
It would be awesome to not have to copy/paste the default template in every app instance since the rest of the template remains the same, just adding some instructions to the top above the property loop.
