Describe the feature you'd like

There are multiple duplicate template files created just to satisfy different grouping requirements. For instance, deep_research.json and deep_research_r.json are exactly the same. This design could be improved. To reduce maintenance costs, I suggest adding support for multiple canvas_types within a single file.
