pull custom actions from state/context into edit action UI

It would be great if there is a way to allow a UI designer to reference custom actions defined in state data to be passed to a custom component via a binding instead of having to use the custom code action editor.

E.G.

Using the multi-page funnel where there is a navigateNext and navigateBack action defined and bound to state, in order to use these within a component, I need to select custom code and enter state.navigateNext(); as javascript.

Could we surface actions defined within state or context more visually in the actions editor?
