Could somebody help me and take a look at this question please?
I want to use a Canvas Content Template as default for a Content Type (e.g. "Projects"), BUT be able to override individual nodes.

Example:

• Template has Title + Subtitle + Image
• For one specific Project node, remove subtitle (or completely different layout)

What I've tried:

1. Content Type → Manage Display → "Allow each content item to have its layout customized" is not a visible option
2. Canvas enabled for View Mode
3. Edit Node → looking for "Layout" tab / Canvas override checkbox → nothing visible

Questions:

1. Where exactly does the "Override default template for this node only" checkbox from Issue #3567225 appear?
2. Do I need to create Content Template first (/canvas/content-templates)?
3. Missing permission or feature not in Canvas 1.0?
4. Is there a Workaround like Custom Block per node or other solution?
