I'm using a template so users can create new "Issue" pages as they need them. Each Issue is rated "High", "Medium" or "Low" so I used a Variable with that List of ratings to select from.

User can create a new issue page with a rating of "High" for example. However, later the user may want to change the rating to "Low" or "Medium". When they edit the page, the list is no longer available (it's only available in Step 2: Fill in template variables). How do I provide a dropdown list (i.e. select in HTML) for users to select from when editing the page?
