End to End modelling of GRC

I have KPI Allocation Diagrams, Risk Diagrams and Business control diagrams. Is there any way I can create an end-to-end diagram having objects in all these models, ie, Objectives, KPIs, Risks, Controls and Tests ? The problem I have is KPI allocation diagrams dont allow Controls, BCDs dont allow Objectives etc.

Our users want to see everything together, without going from one model type to another.

Appreciate inputs on this.
