Expose existing Aha! work items on Create whiteboard

I want to have interactive planning sessions in Aha! Roadmaps using the Create whiteboard. Today, Create allows you to create sticky notes and convert them to epics, features, etc. My use case is when product management has an existing backlog of features and we want to collaborate on a Create whiteboard to plan these features. I want to be able to reveal existing Roadmaps work items on the Create board.
