The diagram lives in a drawing tool, the threat model in a second tool, the control list in a spreadsheet and the sign-off in an inbox. Four documents, maintained by hand, disagreeing within a week.
One record, versioned, instead of four documents.
Describe the intent in a paragraph and Design Studio draws it in your house style. Promote the shapes into a threat model. Every threat maps to a control, and that control lands on the project marked threat-driven, so the Build tab already knows what to implement.
