Problem:
New content slides can currently only be created based on predefined layout categories (e.g., Comparison, Meet the Team). Each layout only allows importing a fixed set of Design Options defined in its associated designOption.json. Additional components cannot be added, which makes layouts unnecessarily rigid and difficult to adapt to custom design requirements or corporate branding.

Example:
Meet the Team only allows paragraph and image-grid. Adding an additional paragraph beneath the grid is not possible.

{
  "type": "Meet the Team",
  "name": "$$name",
  "description": "$$description",
  "designOptionId": "LAYOUTS_MEET_THE_TEAM",
  "isDefault": false,
  "version": "1.0",
  "thumbnail": "thumbnail.png",
  "styles": [
     {
      "tag": "paragraph",
      "designOptionId": "MTT_PARAGRAPH_OPTION_1"
    },
    {
      "tag": "image-grid",
      "designOptionId": "IMAGE_GRID_MTT_OPTION_1"
    }
  ]
}

Suggestion:
Enable support for custom layout slides, where the corresponding designOption.json can contain any components the author needs. This would allow instructional designers to create rich, reusable layout templates for both slide-based content and longpages.
