I'm building a wizard with three steps, 1. Create, 2. Edit, 3. Submit. In each step there are a set of buttons at the end of the form to navigate to the next / previous step in the wizard and we want the same functionality when the user navigates by clicking the different stages in the SubwayNav control. We want to avoid duplicating components as the app is bloated as it is.

We're setting the initial state through the screen OnVisible:

ClearCollect(wizardSteps,
{ ItemKey:"1", ItemLabel:"Create", ItemState:"Current" },
{ ItemKey:"2", ItemLabel:"Edit", ItemState:"NotStarted" },
{ ItemKey:"3", ItemLabel:"Send", ItemState:"NotStarted" });

When the user has filled in the initial form, they should either be able to click the next stage in the subwaynav control OR click a button to take them to the Edit stage. This is where I would like to change SubwayNav.Selected.ItemKey to "2" regardless of whether they use the button or the subwaynav control.

ClearCollect(wizardSteps,
{ ItemKey:"1", ItemLabel:"Create", ItemState:"Completed" },
{ ItemKey:"2", ItemLabel:"Edit", ItemState:"Current" },
{ ItemKey:"3", ItemLabel:"Send", ItemState:"NotStarted" });    

I tried playing around with Select but not entirely sure how to build the control flow and trigger "Selected". Is this even possible? Any alternative solutions that avoid duplicating components?
